Find f'(x) if
1. f(x) = 2x-3 / (x2+1)1/2
2. f(x) = (x2+1)4
3. f(x) = [(x1/2+(x+1)1/2]2

Given h(x)= x+c / (x2+1)1/2 ,where c is a contant.
If h'(0)=2 , find the value of c

列明步驟thx :D
感謝你的幫助!!!
更新1:

沒有! 全部也是對的:)

更新2:

sorry...係我打錯! Given h(x)= x+c / (x2+c)1/2 ,where c is a constant. If h'(0)=2 , find the value of c thx!
