Question

Let f be a differentiable function such that f(0) = -5 and f'(x) is less than or equal to 3 for all x. Of the following, which is not a possible value for f(2)?

Answer 1

Since the function has a slope that cannot go above 3 for all x, f(2) cannot be any value greater than 1.

I may be wrong, but this is what I believe the answer is.
