Question

Find f'(2) when f(x)=g(x)h(x)

Answer 1

you need more information, but
f ' (x) = g'(x) * h(x) + g(x) * h'(x)

Answer 2

that's all it gives.

Answer 3

Answer 4

f ' (2) = g'(2) * h(2) + g(2) * h'(2)

Answer 5

u dnt need a final answer just u need to know how to deffrentiate the multiple of two function.

Answer 6

Can you expand @ikram002p

Answer 11

f'(x)=(h'(x))g(x)+h(x)g'(x)

Answer 12

is that right?

Answer 13

Yes.

Answer 14

how would i find f'(2) for that? just put it into where x is or do i have to expand?

Answer 15

Just plug in x=2.

Answer 16

f'(2)=(h'(2))g(2)+h(2)g'(2) my answer?

Answer 17

Yep
