Question

$$-x+1-8x+3$$

Evaluate

$4-9x$

Differentiate w.r.t. x

$-9$

Steps Using Derivative Rule for Sum

Add $1$ and $3$ to get $4$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-x+4-8x)$$

Combine $-x$ and $-8x$ to get $-9x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-9x+4)$$

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 $nax^{n-1}$.

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

Subtract $1$ from $1$.

$$-9x^{0}$$

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

$$-9$$
