Answer: $-2xe^{-x^2}$

Step-by-step explanation:

Let u be a differentiable function , then

$\dfrac{d}{dx}(e^x)=e^x$

$\dfrac{d}{dx}e^u=e^u\dfrac{du}{dx}$ (1)

Given function : $y = e^{-x^2}$

Differentiate both sides with respect to x , we get

$y'=e^{-x^2}\dfrac{d(-x^2)}{dx}$ (By using (1))

$\Rightarrow\ y'=e^{-x^2}(-2x)$ [∵ $\dfrac{d}{dx}(x^n)=x^{n-1}$ ]

$\Rightarrow\ y'=-2xe^{-x^2}$

Hence, the derivative of the given function is $-2xe^{-x^2}$ .

area of the figure=

$\frac{1}{2} \times (25 + 31) \times \times 11 \\ \frac{1}{2} \times 56 \times 11 \\ 28 \times 11 \\ 308$

$12 \times 14 \\ 168$

$308 + 168 \\ 476$
