To show: the given statement without graphing the inverse.
Answer to Problem 4CFU
If there are more than one values of y for a particular value of x or if a horizontal line touches the function at more than one place then the inverse will not be a function.
Explanation of Solution
Given information:
How to check whether inverse of a function is also a function.
Calculation:
If there are more than one values of y for a particular value of x. In other words, if a function passes the horizontal line test, i.e. a horizontal line touches the function at more than one place then the inverse will not be a function.
