Relation
The mapping between a set of inputs and a set of outputs.
Domain
The set of all input values of a relation.
Range
The set of all output values of a relation.
Discrete Graph
A graph of isolated points.
Vertical Line Test
A visual method used to determine whether a relation represented as a graph is a function.
Function
A relation between a given set of elements for which each input value there exists exactly one output value.
Function Notation
A way to represent equations algebraically that makes it more efficient to recognize the independent and dependent variables.
Exponential Functions
Functions of the form f(x)=a*b^x, where a and b are real numbers, and b is greater than 0 but is not equal to 1.
Linear Piecewise Functions
Functions that have a equation that changes for different parts, or pieces, of the domain.
Increasing Function
Function where both the independent and the dependent variables of a function increase across the entire domain.
Absolute Maximum
Function where there is a point on its graph that has a y-coordinate that is greater than the y-coordinates of every other point on the graph.
Function Family
A group of functions that share certain characteristics.
Linear Absolute Value Function
Functions of the form f(x)=a|x + b| + c, where a, b, c are real numbers and a is not equal to 0.
