Find first derivative f(x)= x² - 4 /x³ + 9

vitfil [10]

Answer:

f'(x) = 2x + $\frac{12}{x^{4} }$

Step-by-step explanation:

differentiate using the power rule

$\frac{d}{dx}$ ( a $x^{n}$ ) = na $x^{n-1}$

Given

f(x) = x² - $\frac{4}{x^3}$ + 9 = x² - 4 $x^{-3}$ + 9 , then

f'(x) = 2x + 12 $x^{-4}$ = 2x + $\frac{12}{x^{4} }$
