When we perform another subtraction:

, we get a number

When we raise

or

to the power of 2, the result is the same,

.
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
