Question 122533: Could you please help me find the f’(x) for the f(x) I believe this is the derivative.
f(x) = 6/X4 , f’(x) =

f(x) = x3 – 2x2 + 3x – 4 , f’(x) =

f(x) = 2 x – 3x 5/3 , f’(x) =

Thank you so much for your help!

For polynomials of the form,
f(x)=a%5Bn%5D%2Ax%5En+a%5Bn-1%5D%2Ax%5E%28n-1%29+...+a%5B1%5D%2Ax%2Ba%5B0%5D
The derivative, f'(x), is given by,
f'(x)=n%2Aa%5Bn%5D%2Ax%5E%28n-1%29+%28n-1%29%2Aa%5Bn-1%5D%2Ax%5E%28n-2%29+...+a%5B1%5D
1.f(x)=6%2Fx%5E4
f(x)=6x%5E%28-4%29
f’(x)=%28-4%296x%5E%28-4-1%29
f’(x)=-24x%5E%28-5%29
f’(x)=-24%2Fx%5E%285%29
2.f(x)=x%5E3-2x%5E2%2B3x-4
f'(x)=3%2Ax%5E%283-1%29-2%2A2x%5E%282-1%29%2B3
f'(x)=3%2Ax%5E%282%29-4x%2B3
3.f(x)=2x-3x%5E%285%2F3%29
f’(x)=2-5x%5E%282%2F3%29
