$4 x - 5$

Step 1

By the Sum Rule, the derivative of $4 x - 5$ with respect to $x$ is $\frac{d}{d x} [4 x] + \frac{d}{d x} [- 5]$ .

$\frac{d}{d x} [4 x] + \frac{d}{d x} [- 5]$

Step 2

Evaluate $\frac{d}{d x} [4 x]$ .

Step 2.1

Since $4$ is constant with respect to $x$ , the derivative of $4 x$ with respect to $x$ is $4 \frac{d}{d x} [x]$ .

$4 \frac{d}{d x} [x] + \frac{d}{d x} [- 5]$

Step 2.2

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 1$ .

$4 \cdot 1 + \frac{d}{d x} [- 5]$

Step 2.3

Multiply $4$ by $1$ .

$4 + \frac{d}{d x} [- 5]$

Step 3

Differentiate using the Constant Rule.

Step 3.1

Since $- 5$ is constant with respect to $x$ , the derivative of $- 5$ with respect to $x$ is $0$ .

$4 + 0$

Step 3.2

Add $4$ and $0$ .

$4$
