The inverse function is:
And g(2) = 212.
<h3>How to get the inverse function?</h3>
We need to find g(x) such that:
g(h(x)) = x.
We know that:
Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:
As you can see, if you evaluate in h(x), the outcome is x.
Now we can evaluate this in x = 2, we get:
The correct option is C.
