Input In a relation, inputs are associated with outputs.
Output In a relation, inputs are associated with outputs.
Relation A relation pairs inputs with outputs and can be represented by ordering pairs on a mapping diagram
Mapping Diagram A way to represent a relation
Function A relation that pairs each input with exactly one output The ordered pairs (0,1) (1, 2) (2, 4) and (3, 6) represent a function.
Function Rule An equation that describes the relationship between inputs (independent variable) and outputs (dependent variable) The function rule “The output is three less than the input” is represented by the equation y = x − 3 .
Linear Function A function whose graph is a nonvertical line; a function that has a constant rate of change
Nonlinear Function A function that does not have a constant rate of change; a function whose graph is not a line
