$\mathfrak{\huge{2}}$

$\underline{\purple{\mathfrak{Explanation:-}}}$

Given

y = 2x

$\dfrac{dy}{dx} =\dfrac{d(2x)}{dx}$

$\dfrac{dy}{dx} =(2)\dfrac{d(x)}{dx}$

$\dfrac{dy}{dx} = (2) (1)$

$\dfrac{dy}{dx} = 2$

Identities used:

If, y = x THEN

$\dfrac{dy}{dx} =</strong> n<strong> </strong><strong>\</strong><strong>times </strong><strong>{</strong><strong>x</strong><strong>}</strong><strong>^</strong><strong>{</strong><strong>n-1</strong><strong>}</strong><strong>$
