Question

Need help with a calculus problem. Problem in comments

Answer 1

Check what h'(x) is in general. The problem states that in this particular case, h'(x) = f(x)*g'(x), so what does that tell you about f'(x)?

Answer 2

In general you have h(x)=g(x).f(x)
if we differentiate h'(x)
we have h'(x)=g'(x)f(x)+g(x)f'(x) which is given to us like this h'(x)=g'(x)f(x)
so what does this mean

Answer 3

so f'(x)=0 yes?

Answer 4

I agree with you. @katiestyles212

Answer 5

if f'(x)=0 what does that mean?

Answer 6

in kind of functions give us zero if we differentiate them?

Answer 7

I have no idea. I thought f(x) would equal 1

Answer 8

hmmm yes it would be 1 but
do you understand why?

Answer 9

f' always tell us information about f(x)

Answer 10

Yes I got it now, thanks

Answer 11

hmm Ok!
