Which function is the inverse of f(x)=-x³-9?

Inverse of f(x)=-x^3-9 is

Option B is correct option.

Step-by-step explanation:

We need to find inverse of

For finding the inverse replace f(x) with y

Now, solve for x

Adding 9 on both sides

Multiply both sides by -1

Taking cube root on both sides:

Now replace x with f^{-1}(x) and y with x

So, inverse of f(x)=-x^3-9 is

Option B is correct option.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
