Step 1.1

By the Sum Rule, the derivative of

3 - x^{2}

$3 - x^{2}$ with respect to

x

$x$ is

\frac{d}{d x} [3] + \frac{d}{d x} [- x^{2}]

$\frac{d}{d x} [3] + \frac{d}{d x} [- x^{2}]$ .

\frac{d}{d x} [3] + \frac{d}{d x} [- x^{2}]

$\frac{d}{d x} [3] + \frac{d}{d x} [- x^{2}]$

Step 1.2

Since

3

$3$ is constant with respect to

x

$x$ , the derivative of

3

$3$ with respect to

x

$x$ is

0

$0$ .

0 + \frac{d}{d x} [- x^{2}]

$0 + \frac{d}{d x} [- x^{2}]$

0 + \frac{d}{d x} [- x^{2}]

$0 + \frac{d}{d x} [- x^{2}]$

Step 2

Evaluate

\frac{d}{d x} [- x^{2}]

$\frac{d}{d x} [- x^{2}]$ .

Step 2.1

Since

- 1

$- 1$ is constant with respect to

x

$x$ , the derivative of

- x^{2}

$- x^{2}$ with respect to

x

$x$ is

- \frac{d}{d x} [x^{2}]

$- \frac{d}{d x} [x^{2}]$ .

0 - \frac{d}{d x} [x^{2}]

$0 - \frac{d}{d x} [x^{2}]$

Step 2.2

Differentiate using the Power Rule which states that

\frac{d}{d x} [x^{n}]

$\frac{d}{d x} [x^{n}]$ is

n x^{n - 1}

$n x^{n - 1}$ where

n = 2

$n = 2$ .

0 - (2 x)

$0 - (2 x)$

Step 2.3

Multiply

2

$2$ by

- 1

$- 1$ .

0 - 2 x

$0 - 2 x$

0 - 2 x

$0 - 2 x$

Step 3

Subtract

2 x

$2 x$ from

0

$0$ .

- 2 x

$- 2 x$

$3 - x^{2}$
