Answer:

Step-by-step explanation:
So we have the function:

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

Add 9 to both sides:

Take the natural log of both sides:

The right side cancels:

Divide both sides by 6:

And we're done!
I think it is 36^2+12ab+b^2
Do you mean 90(3n-6) if so the answer is -270 but if you mean 3n-6 the answer is -3
