Equation
A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Inequality
The relation between two expressions that are not equal, employing a sign such as ≠ "not equal to," > "greater than," or < "less than."
Positive
A number that is greater than zero.
Negative
A number that is less than zero.
Axes
Fixed reference lines for the measurement of coordinates.
Table
Numbers or quantities arranged in rows and columns.
Independent
A variable (often denoted by x ) whose variation does not depend on that of another. This variable causes the change in another variable.
Dependent
A variable (often denoted by y ) whose value depends on that of another. This variable is the effect of the change in another variable.
Function
A relationship or expression involving one or more variables, where each independent value (the input) has only one dependent value (the output).
Area
The size of a surface of a two-dimensional figure.
Relationship
When one variable quantity appears to change right along with another variable. It could also be one variable causing a change in another.
Domain
All reasonable numbers that could be used to quantify the independent variable.
Range
All reasonable numbers that could be used to quantify the dependent variable.
Continuous
Numbers that include all of the integers on the number line, and all the fractional numbers in between. Example: The amount of flour in a mixing bowl. You can have one full cup or 1/2 or even 0.2 cups of flour.
Discrete
The integers on the number line but not the numbers in between them. Example: IPads, because you can have 1 IPad, 2 Ipads and so forth, but you cannot have 1/2 of an IPad.
Intervals
A list of numbers in a sequence. For instance, [1,10] means all numbers between 1 and 10 including 1 and 10, and all of the fractional numbers in between.
Scatter Plot
An x and y-axis graph with a bunch of coordinate points (dots) on it.
Positive correlation
The dots on the scatter plot are trending upward from left to right.
Negative correlation
The dots on a scatter plot are trending downward from left to right.
Polynomial
An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Expression
A combination of symbols and terms that look like an equation but are missing an equals sign.
Factor
Means to break numbers and equations up into parts that can be multiplied together to get the original number or equation.
Linear
Resembling a straight line.
Standard form
The form of a linear equation before it has been solved for y. Ax+By=C
Slope
A number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line. Also called rise over run.
Intercept
The point where a line goes through the x or y-axis.
Slope-intercept form
Some call this "y=" form. It is y=mx+b
Data set
Numbers that have been collected to represent changes in the independent and dependent variable quantities.
X-intercept
The point where the line goes through the x-axis.
Y-intercept
The point where the line goes through the y-axis.
Rate of change
The speed at which a variable changes over a specific period of time.
Increasing Function
The line on the graph is going up from left to right.
Decreasing Function
The line on the graph is going down from left to right.
Steeper
Rising at a higher rate . This usually refers to the slope of a line. The angle between the line and the x-axis gets larger.
Solution set
A group of numbers that can satisfy an equation or a situation involving a problem.
Intersection
A place where two lines on a graph meet.
System of linear equations
A collection of two or more equations with the same set of variables. The solution is where the lines for the equations intersect.
Plot
To place coordinate points in their respective locations on a graph.
Parabola
A -shaped line on a graph formed by the equation y=x^2.
Quadratic
Refers to the relationship between two variables, where as one quantity rises (or falls) the other does too, but then goes in the opposite direction up or down.
Projectile
An object propelled or launched with great force.
Time versus Distance
The first is an independent variable and the second is a dependent variable.
Roots
A place where a parabola passes through the x-axis.
Quadratic equation
An equation with its highest exponent being a squared.projectile
Solution
The value of x when solving an equation.
Zeros of quadratic
The place where the parabola passes through the x-axis. The name comes from the fact that the y-values at these intercepts are 0.
X-intercepts of quadratic
The places where the parabola goes through the x-axis. The name comes from the fact that the parabola touches the x-axis.
Quantity
A certain amount of something.
Variable
A letter representing an unknown and changing quantity.
Parent function
Equations with the basic building blocks for more complicated equations. Examples of this are y=x and y=x^2.
Decline
A decrease in amount.
Parabolic
U-shaped on the graph.
Exponential
Growth happening very fast. The equation for this must have a variable in the exponent spot. The pattern for this is growth by a factor of some number.
Functional notation
Commonly f(x) pronounced "f of x."
Commutative
Being able to switch the order of numbers when, for instance, multiplying and adding.
Associative
Being able to, for instance, multiply in a different order to get the same result.
Distributive
Lets you multiply a sum by multiplying each addend separately and then add the products.
Equivalent
One is the same as the other.
Monomial
An equation or expression with only one term.
Binomial
An equation or expression with only two terms with different numbered exponents.
Trinomial
An equation or expression with only three terms with different numbered exponents.
Constant rate
Going up or down by the same amount.
Constant
A number term with no variable.
Coefficient
A number term containing a variable.
Set notation
A precise way of describing which items belong in a set and which do not.
Real numbers
All numbers--positive and negative integers and fraction/decimal. This includes the number zero. Does not include imaginary or irrational.
Function rule
The expression part of an f(x) equation such as 2x-3.
Proportion
Two ratios that are equal to each other.
Direct variation
An equation with y and x, containing a slope but no y-intercept.
Unit rate
A way in which a quantity is measure.
Reasonableness
The answer reached in solving just seems to make sense.
Estimate
An approximation or a rounding of a number.
Exponents
Small numbers in the superscript of an exponential. We say "raised to the power of..."
Exponential functions
Exponential equations with one output for every one input. It involves the notation f(x).
Exponent laws
Seven rules that dictate how to multiply and divide exponential numbers.
Inverse variation
A process in which variables y and x in an equation are switched and we solve for y.
Nonlinear functions
A line on a graph that is not straight.
Exponential growth and decay
The quantity of something that increases or decreases very fast. The equation has a variable in the exponent spot. Increases have a positive exponent and decreases have a negative exponent.
Vertex
The highest or lowest point of a function. It is a measure of location/coordinate point.

The distance around an object at its base.
Simplify
Combining like terms and eliminating parentheses by multiplying.
Labor
The effort put out at work.
