coordinate plane
A coordinate system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.
ordered pair
A pair of numbers, (x, y), that indicate the position of a point on a Cartesian plane.
term
a number, a variable, or the product of a number and a variable
variable
A letter or symbol used to represent a number.
sum
a quantity obtained by addition
difference
the number that remains after subtraction
quotient
the number obtained by division
product
a quantity obtained by multiplication
coefficient
number in front of a variable
constant
a quantity that does not vary
domain
the set of values of the independent variable for which a function is defined
range
The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation.
combine like terms
add or subtract the coefficients of the variables
algebraic expression
A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.
integer
The set of whole numbers and their opposites
function
an input-output relationship that has exactly one output for each input
operation
calculation by mathematical methods
expression
a group of symbols that make a mathematical statement
exponent
indicates the number of times a quantity is multiplied by itself
square number
the product of a number and itself
slope
the steepness of a line on a graph, equal to its vertical change divided by its horizontal change
y-intercept
where the line crosses the y axis
monomial
an expression with only one term
polynomial
a mathematical expression that is the sum of a number of terms
linear equation
a polynomial equation of the first degree
Intercept
the point at which a line intersects a coordinate axis
Intersecting lines
Lines that cross
Minimum
the smallest possible quantity
Maximum
the largest possible quantity
Constant Difference
the difference that is always the same from one term to the next number
Negative Exponent
an exponent less than zero which causes the base and its exponent to move positions in a fraction
Slope
the steepness of a line on a graph, equal to its vertical change divided by its horizontal change
Quadratic Function
a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero
Exponential Function
a function in which an independent variable appears as an exponent
Square Root Function
A function that contains a square root of a variable.
Cubic Functions
Third degree polynomial functions.
Axis of Symmetry
a line that divides a figure into 2 congruent parts
