# Find the second order derivatives of the functions given in $x^2 + 3x + 2$

$\begin{array}{1 1} 2 \\ 3 \\ 2x+3 \\ 2x \end{array}$

Can you answer this question?

Toolbox:
• $y=f(x)$
• $\large\frac{dy}{dx}$$=f'(x) • \large\frac{d^2y}{dx^2}=\frac{d}{dx}\big(\frac{dy}{dx}\big) Step 1: Let y=x^2+3x+2 Differentiating with respect to x \large\frac{dy}{dx}$$=2x+3$
Step 2:
$\large\frac{d^2y}{dx^2}=\frac{d}{dx}$$(2x+3)$
$\quad\;\;\;=2$
