@Gator, yeah that’s all the info, exact problem statements:

Given f(x) is continuous and differentiable for all x, if f(3) = 5 then f’(3) =

Given f(x) is continuous and differentiable for all x, differentiate both sides of the following equation: f(3) = 5

@mathprof, it also makes sense to me why the second one would be 0 = 0, since f(3) is constant because its value IS 5. The first question is still a bit baffling.

Anyways, I just thought this set of questions was kind of interesting.
