Answer:
Step-by-step explanation:
To find a function's inverse, you first switch the x and y coordinates, and then solve for the new y. The same goes for finding an inverse's function. We have:
We will switch the x and y variables and then solve for the new y:
and
11x = y + 4 so
11x - 4 = y and
11x - 4 = f(x) which is choice C.
