just wanted to check if im correct and also wanted to know how i would do the last two...d and e

I have the answers for the first 3...

a)(f-g)'(0) $\displaystyle f'(0) - g'(0) = 1 - 3 = -2$

b)(fg)'(1) $\displaystyle f'g + fg' = (2*4)+(3*1) = 11$

c) (f/g)'(2)$\displaystyle (f'g-g'f)/g^2 = ((3*4)-(4*4))/(2^2) = -1$

just wanted to know if im correct for those ones...and i dont know how to do the conposite functions of of d and e..how would i go on about doing those??
