OBJECTIVE 1

(a) (b) {(1,5), (2,8), (3,11), (4,14)} Student Car Dan John Joe Andy Saturn Pontiac Honda

For each function, use the graph to determine whether the function is one-to-one. (a) (b)

A function that is increasing on an interval I is a one-to-one function in I. A function that is decreasing on an interval I is a one-to-one function on I.

OBJECTIVE 2

Find the inverse of the following function Find the inverse of the following function. Let the domain of the function represent certain students, and let the range represent the make of that student’s car. State the domain and the range of the inverse function. Student Car Dan John Joe Michelle Saturn Pontiac Honda Chrysler

{(1,5), (2,8), (3,11), (4,14)} State the domain and the range of the function and its inverse.

OBJECTIVE 3

The graph shown is that of a one-to-one function The graph shown is that of a one-to-one function. Draw the graph of the inverse. (1,4) (0,3) (-1,0)
