Contextual Situation - real-life scenarios or circumstances that illustrate mathematical problems

Continuous - Data that can take any values within a certain interval

Domain- the set of all first elements of ordered pairs

Dependent Variable - a variable in an expression, equation, or function that has its value determined by the choice of the value(s) of other variable(s)

Discrete - Data that can only take certain values

Function - a relation where each input has a single output

Function Notation - a method of writing algebraic variables as functions of other variables

Function Rule - an expression that

Graph of a Function- the set of all points that represent a function on the coordinate plane

Independent Variable- the variable in an expression, equation or function whose value determines the value of other variables

Input - the value substituted into a function (see independent variable)

Intercept - a point at which a graph intersects the x-axis or y-axis

Ordered Pairs - two numbers used to provide the location of a point on the coordinate plane

Output - the value generated in a function from an input (see dependent variable)

Parent Function - the simplest function in a family of functions that preserves the shape of the entire family

Range - the set of all second elements of ordered pairs

Rate of Change - the ration of the change in the value of a variable over a period of time

Relation - the set of all second elements of ordered pairs

Slope - the ratio of the change in dependent values to the change in independent values

Table of a Function - input and output values in table form

Vertical Line Test - visual way to determine if a graph is a function or not
