#### Definitions

Algebraic Base The number or variable raised to a power
Compound Inequality Two inequality statements combined into one using the words AND or OR.
Domain The complete list of x-values of a relation or function
Irrational Number Numbers that can not be represented as a fraction such as radicals and pi
Evaluate Use order of operations to find the value of the expression
Polynomial The sum or difference of two or more monomials
Absolute Value A number's distance from zero
Line of Best Fit A line drawn on a scatterplot to best represent a set of data
Quadrant Any of the four regions formed by the coordinate system
Y-intercept The value of y where a graph crosses the y-axis
Arithmetic Sequence An ordered list of numbers that increase or decrease at a constant value
Slope The change in y divided by the change in x; variable m
Rule A mathematical expression that describes a pattern
Extrapolate To estimate a value or quantity beyond the known range of data
Perpendicular Slopes Slopes that are opposite reciprocals
Factoring Writing an algebraic expression as a product of two expressions
System of Linear Equations Two or more linear equations with no common, one common or infinitely many common solutions
Range A complete set of y-values of a function
Extraneous Solution Math Solutions not necessary to solve the problem
Associative Property Adding or Multiplying values or algebraic expressions in any order:
(A + B) + C = A + (B + C)
Commutative Property Flipping a product or sum does not effect the value of the expression:
A D = D A
Point-Slope Form Y - Y1 = m (X - X1)
Union of Sets The set of elements which are in set A or in Set B or in both sets.
A U B
Venn Diagram A diagram that shows relationships among sets of objects
Distributive Property The product of a number and the sum or difference of two numbers is equal to the sum or difference of the two products.
A(B + C) = AB + AC
Order of Operations PEMDAS: Parenthesis, Exponents, Multiplication/Division from left to right, Addition/Subtraction from left to right
Complement of a Set A Denoted by ~A. The set of all elements that are not in set A.
Coordinate Plane x and y axis that are used to display functions and data
Literal Equation An equation involving two or more variables
Whole Numbers {0,1,2,3,4,.....}
Proportion A mathematical equation that says two ratios are equal.
Identity Property A number added with 0 is equal to the number. 4 + 0 = 4
Inverse Operation An operation that undoes a previously applied operation. Subtraction is the inverse of Addition
Quadratic Equation A polynomial equation what has a variable raised to the second power and no higher
Relation A set of ordered pairs
Divisor The number by which another number is divided.
Binomial Polynomial with two terms
Equivalent Expressions two expressions that have the same value written differently
Function a relation where every x is paired with only one y
Axis of Symmetry Vertical line that cuts parabola into two equal pieces
-b/2a X-coordinate of the vertex of a parabola
Rate ratio that compares two quantities of different units
Rate of Change ratio of one quantity to the change in another quantity
Real Number Any number, decimal, fraction or radical
Radical Symbol used for square roots and other roots
Variable Symbol used to describe unknown value
Transformation Reflections, Translations (slides), Stretches of a function
Estimation the use of rounding or other strategies to determine a reasonable approximation without calculating the actual answer
Coefficient The number that multiplies the variable(s) in an algebraic expression. If no number is present, the coefficient is one
Subset A set in which the members are all contained in another set
Slope-intercept form of a line y = mx + b
Intersection The point at which two functions meet
Integers {....-4,-3,-2,-1,0,1,2,3,4,.......}
Inequality Rule When multiplying or dividing by a negative, switch the inequality symbol.
Exponent Power
Pattern A predictable sequence of numbers, objects, etc.
Linear Inequality Lines that are dashed/solid with shading
Natural Number {1,2,3,4,5,......}
Negative Exponent designates reciprocal of a number or expression
Origin(0,0)
Slopes of Parallel Lines same slopes
Similar Figures Figures that have corresponding sides that are proportional in length
