Chapter 5: Q. 85 (page 270)

A function $f$ has an inverse function. If the graph of $f$ lies in quadrant I in which quadrant does the graph of $f^{- 1}$ lie?

Short Answer

Expert verified

The graph of $f^{- 1}$ lies in the first quadrant

Step by step solution

Given information

Given the function $f$ has an inverse function

Checking the reason

The graphs of a function $f$ and its inverse are mirror images (or reflections) of each other about the line $y = x$

Hence, if the graph of a function $f$ is in Quadrant I, then the graph of its inverse is its reflection about the line $y = x$ . Note that when a graph in Quadrant I is reflected about the line $y = x$ , the reflection is also in Quadrant I.
