Question

$$x(|7|)$$

Differentiate w.r.t. x

$7$

Steps Using Definition of a Derivative

The absolute value of a real number $a$ is $a$ when $a\geq 0$, or $-a$ when $a<0$. The absolute value of $7$ is $7$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(x\times 7)$$

The derivative of $ax^{n}$ is $nax^{n-1}$.

$$7x^{1-1}$$

Subtract $1$ from $1$.

$$7x^{0}$$

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

$$7\times 1$$

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

$$7$$
