Question

$$3 { x }^{ 3 } +2x+7$$

Differentiate w.r.t. x

$9x^{2}+2$

Steps Using Derivative Rule for Sum

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is $0$. The derivative of $ax^{n}$ is $nax^{n-1}$.

$$3\times 3x^{3-1}+2x^{1-1}$$

Multiply $3$ times $3$.

$$9x^{3-1}+2x^{1-1}$$

Subtract $1$ from $3$.

$$9x^{2}+2x^{1-1}$$

Subtract $1$ from $1$.

$$9x^{2}+2x^{0}$$

For any term $t$ except $0$, $t^{0}=1$.

$$9x^{2}+2\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$9x^{2}+2$$

Evaluate

$3x^{3}+2x+7$
