What is the inverse of the function f (x) = x - 12? h (x) = 48x - 4 h (x) = 48x + 4 h (x) = 4x - 48 h (x) = 4x + 48

Let h be the inverse function of f,

then we have f (h (x)) = x.

According to the formula f (x) = x-12, we have f (h (x)) = h (x) - 12. But we also know that f (h (x)) = x.

So we equalize h (x) - 12 and x:

h (x) - 12=x, which gives us the function h (x) = x+12.

Answer: h (x) = x+12
