Question

You are told that f is a one-to-one function with values f(3)=7 and f(-5)=-10

Answer 1

Answer:

Explanation:

The inverse function gives back the input of the original function when we put in the original output.

In other words, if the original function does the following.

f(input) = output

Then the inverse function does the following.

f^-1(output) = input

Now in our case, we have f(3) = 7; therefore, the inverse function should give

$\boxed{f^{-1}\left(7\right)=3.}$

If we have f( -5) = - 10, then the inverse function should give

$\boxed{f^{-1}(-10)=-5.}$

Hence, choices 1 and 5 are the correct answers!
