Question

I need help with my Pre-Calculus HW! The directions say "given f(x) and g(x), determine if f and g are inverse functions."

Answer 1

We will have the following:

1.

`y=-(x+1)^3`

Thus:

`x=-(y+1)^3\Rightarrow y=-\sqrt[3]{x}-1`

So, g(n) is not the inverse function.

2.

`y=(-16+x)/(4)`

Thus:

`x=(-16+y)/(4)\Rightarrow y=4x+16`

So, g(n) is the inverse function.
