Question

What is the inverse of this function? f(x)=x−7

Answer 1

Answer:

f^−1(x) = x + 7

Step-by-step explanation:

Replace f(x) with y. y = x − 7

Interchange the variables.  x = y − 7

Solve for y.  y = x + 7

Solve for y and replace with f^−1 (x).  f^−1(x) = x + 7

I hope this helps have a great day :)
