Question

if y=4x^3-7x^4 then what is for dy/dx​

Answer 1

Answer:

$\boxed{\tt\implies \frac{dy}{dx} = {12x}^{2} - {28x}^{3} }$

Step-by-step explanation:

$\bf\red{y = {4x}^{3} - 7 {x}^{4} } \\ \\ \tt\implies \: \frac{dy}{dx} = \frac{d}{dx} \: {4x}^{3} - \frac{d}{dx} {7x}^{4} \\ \\ \tt\implies \frac{dy}{dx} = 4. {3x}^{2} - 7 .{4x}^{3} \\ \\ \boxed{\tt\implies \frac{dy}{dx} = {12x}^{2} - {28x}^{3} }$
