[Blindmath] Derivatives Help

[Joseph Lee]

Hi,
I don't think it's quotient rule, as the expression indicates that product
rule should be used. As Sarah said, what are f(x) and g(x) in this problem,
and does it ask that h(x) be derivative of F times G?
Cheers,
Joseph

Do you have the original f(x) and g(x)? You'll have to differentiate first
with the quotient rule, then substitute 3 in.

I am so lost on this problem and I feel like I can solve it, but I just
don't know where to begin or what to do. The problem is.

Find h'(3) when h(x)=f(x)*g(x)

g(3)=4

G'(3)=5

F(3)=9

f'(3)=8
