Equations
A letter that represents an unknown value
Variable
The set of all x-values of a relation or function
Domain
Where a graph crosses the y-axis (the y-value when x=0)
The number that appears the MOST in a set of data
Mode
A number that can be written as a fraction
Rational number
For any real numbers a, b, and c...
a(b + c) = ab + ac
Distributive property
A term with no variable (a number by itself)
constant
The set of all y-values of a relation or function
Range
The measure of steepness of a graph (calculated by rise or run)
Slope or rate of change
The number that lies in the middle of an ordered dataset (from lowest to highest)
Median
A pair of numbers (x, y) used to identify a point on a coordinate plane
Ordered Pair
For any real numbers a, b, and c...
(a + b) + c = a + (b + c)
Associative Property (change grouping)
The number in front of (multiplied by) a variable
Coefficient
Every input has only ONE output (x-values do not repeat)
Function
U shaped curve - shape of a quadratic function
Parabola
The average of a data set, found by adding all the numbers together and dividing the sum by how many numbers that are in the dataset.
Mean
An integer that evenly divides another integer
Factor
For any real numbers a, b, and c...
a + b + c = c + b + a
Commutative Property (change order)
Terms with the same variables raised to the same exponent
like terms
A function with one or more variables where the exponent of the variable is one (y = mx + b)
Linear Function
The x-value(s) that make a quadratic equation true when set equal to zero.
Roots, zeros, solutions, x-intercepts
Three values that split sorted data into four parts
Quartile
Degree
If the product is zero, then one or both of the numbers being multiplied must be zero.
Zero Product Property
Two operations that undo each other, such as addition and subtraction
A polynomial with a degree of 2
Quadratic
AKA the turning point
Vertex
A numerical value that measures that strength of a linear relationship
Correlation Coefficient
When terms of an expression are written in order from largest exponent to smallest
Standard Form
Addition: the sum of any number and zero is that number.
Multiplication: the product of any number and one is that number.
Identity Property
