Answer:

$\frac{dy}{dx} = 24 x + 21$

Step-by-step explanation:

Explanation:-

Given that the function

y = f(x) = 3 x ( 4 x + 7)

y = 3 x ( 4 x + 7)

y = 12 x² + 21 x ..(i)

Differentiating equation (i) with respective to 'x' , we get

$\frac{dy}{dx} = 12 (2x) +21 (1)$

$\frac{dy}{dx} = 24 x + 21$
