(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

F(3)=−2, g(3)=9, f′(3)=−2, and g′(3)=2, find the following numbers:

(a) (f+g)′(3)

(b) (fg)′(3)

(c) (f/g)′(3)

(d) (f/(f−g))′(3)

3. The attempt at a solution

I already have (a) and (b) [a=0 and b=-22]

for (c) i tried:

(g(x)*f'(x) - f(x)g'(x)) / (g(x))^2

evaluate at 3:

(9)(-2) - (-2)(2) / 4

-18 + 4 / 4

-14/4

-7/2

WHICH IS THE WRONG ANSWER

(d) I just cant get started.
