Integrating the function first and then applying limits, we get:

$\Phi (x)=\frac{2}{3}\left [ (x^{2})^{1.5}-0 \right ]$  $=$  $\frac{2}{3}x^{3}$

$\frac{d}{dx}(\frac{2}{3}x^{3})=2x^{2}$

Option A is correct.

Maxima and minimum of the function $f(x)=2x^3-15x^2+36x+10$ occur; respectively at $x=3$ and $x=2$ $x=1$ and $x=3$ $x=2$ and $x=3$ $x=3$ and $x=4$
