Answer:
D
Step-by-step explanation:
So we have the function:
And we want to find its inverse.
To find the inverse of a function, we need to: 1) change f(x) and x, 2) change f(x) to f⁻¹(x), and 3) solve for f⁻¹(x) for the inverse.
So, flip f(x) and x:
Change:
Solve. Add b to both sides. The right side cancels:
Divide both sides by a:
So, our answer is D.
