If f(x) = 3 − 2x, find f −1(−11).

Inactive Tutor

This does not make sense.....what is "f-1(-11)"? If is f^-1, does that maybe mean the inverse function?

I agree with Mark H. The problem is quite easy if you mean the inverse function. But the lesson here is that you need to exercise care in submitting questions clearly and correctly; sloppy work will NOT suffice in mathematics.
