Explanation:

Step1: Rewrite the function

Rewrite $y = \frac{4}{3x^{2}}$ as $y=\frac{4}{3}x^{- 2}$.

Step2: Apply power - rule for differentiation

The power - rule states that if $y = ax^{n}$, then $\frac{dy}{dx}=anx^{n - 1}$. Here $a=\frac{4}{3}$ and $n=-2$. So, $\frac{dy}{dx}=\frac{4}{3}\times(-2)x^{-2 - 1}$.

Step3: Simplify the derivative

$\frac{dy}{dx}=-\frac{8}{3}x^{-3}$. Then, rewrite without negative exponents: $\frac{dy}{dx}=-\frac{8}{3x^{3}}$.

Answer:

$-\frac{8}{3x^{3}}$
