Target: I can understand and use function notation.

Function Notation Output Input Name of Functio n

A Linear Function f is defined by the equation Where m and b are numbers x= input and y=output and m is the slope or rate of change.

Linear Function Definition A linear function is any function that graphs a straight line.
