Question

$$3 x - 4 2 x + 1$$

Evaluate

$1-5x$

Differentiate w.r.t. x

$-5$

Steps Using Derivative Rule for Sum

Multiply $4$ and $2$ to get $8$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(3x-8x+1)$$

Combine $3x$ and $-8x$ to get $-5x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-5x+1)$$

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 $nax^{n-1}$.

$$-5x^{1-1}$$

Subtract $1$ from $1$.

$$-5x^{0}$$

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

$$-5$$
