1. If f(x)=3(root x)*(x^3-7(root x) +7)
find f'(x) and f'(4)
2. If f(x)=9x+2 / x^2+2x-3, find the derivative f'(x).
3. G(x)=(3x^2-2)(x+2)^2 / (10x^2+8x+2)
4. f(x)=x^8 h(x)
I attempted all of these, thought I was doing everything correct but apparently I was not and now im stuck. Any help is greatly appreciated
