Does f have an inverse O No If so find the following If an a

Does f have an inverse? O No If so, find the following. (If an answer does not exist, enter DNE.) f-1(6) =

Solution

f^-1(-2)

We have to find the value of x when y=-2

And when y=-2, x=0

Therefore

f^-1(-2) =0

f^-1(6)

We have to check for the value of x when y=6

ANd y=6 at x=8

Therefore f^-1(6) =8
