Question

Which represents the inverse of the function f(x) = 4x?Oh(x) = x + 4O h(x) = x- 4O h(x) = 3/4xO h(x) = 1/4x

Answer 1

If h is the inverse function of f, then:

`f(h(x))=x=h(f(x))`

Evaluate f on each option to find which of them corresponds to the inverse function:

1) h(x)=x+4

`f(h(x))=f(x+4)=4(x+4)=4x+16`

2) h(x)=x-4
