Answer 1

Answer:

$\frac{dy}{dx}$ = 2x + 3

Step-by-step explanation:

The gradient function is the derivative $\frac{dy}{dx}$

Differentiate using the power rule

$\frac{d}{dx}$ (a$x^{n}$ ) = na$x^{n-1}$ and $\frac{d}{dx}$ ( constant ) = 0

Given

y = x² + 3x + 1, then

$\frac{dy}{dx}$ = 2$x^{2-1}$ + 3$x^{1-1}$ + 0 = 2x + 3$x^{0}$ = 2x + 3 ← gradient function
