Question

Discrepancy of d/dx (x+3x-4x²)=?​

Answer 1

Answer:

Y = ( x + 3x - 4x² )

Differnatatiating with respect to X

$\frac{dy}{dx } = \frac{d(x + 3x - 4x {}^{2}) }{dx}$

$\frac{dy}{dx} = \frac{d(x)}{dx} + \frac{d(3x)}{dx} - \frac{d(4x {}^{2} )}{dx}$

$\frac{dy}{dx} = 1 + 3 - 8x$

$\frac{dy}{dx } = 4 - 8x$
