Answer 2

$\huge\mathcal{\fcolorbox{cyan}{black}{\pink{ANSWER}}}$

$y = {x}^{3} \\ \implies \: \frac{d \: y}{dx} = \frac{d \: {x}^{3} }{dx} \\ \implies \: \frac{dy}{dx} = 3 {x}^{2} \\ \implies \: \frac{ {d}^{2} y}{d {x}^{2} } = \frac{d \: 3{x}^{2} }{dx} \\ \implies \: \frac{ {d}^{2} y}{d {x}^{2} } = 6x$
