(1 pt) If , find .
=(3x^(3)-6)x^-4 = 3x^(-1)-6
f ' (x) = -3/x^2
If find .
f ' (x) = (12x+2)/(2x^(3/2))
whats the error?
we should see your work to determine if it correct or wrong.
Try to simplify the function first; to make the differentiation step easier.
1- $\displaystyle \frac{3x^3-6}{x^4}=\frac{3}{x}-\frac{6}{x^4}=3x^{-1}-6x^{-4}$.
2- $\displaystyle \frac{4x^2+2x+2}{\sqrt{x}}=4x^{\frac{3}{2}}+2\sqrt {x}+2x^{-\frac{1}{2}}$.
