Question

Which of the following is the inverse of F(x) if F(x)=x+13

Answer 1

The correct answer is F(x)=x-13

Steps:

Replace f(x) with y

.

y=x+13

Interchange the variables.

x=y+13

Solve for y

y=x−13

Solve for y

and replace with f−1(x)

.

f−1(x)=x−13

Answer 2

I don't know the answer choices but the inverse is F(x)=-x-13.
