Step 2.1.1

Replace the variable $x$ with $x + h$ in the expression.

$f (x + h) = \frac{7}{t^{2}}$

Step 2.1.2

The final answer is $\frac{7}{t^{2}}$ .

$\frac{7}{t^{2}}$

Step 2.2

Find the components of the definition.

$f (x + h) = \frac{7}{t^{2}}$

$f (x) = \frac{7}{t^{2}}$

$f (x + h) = \frac{7}{t^{2}}$

$f (x) = \frac{7}{t^{2}}$

Step 3

Plug in the components.

$\frac{f (x + h) - f (x)}{h} = \frac{\frac{7}{t^{2}} - (\frac{7}{t^{2}})}{h}$

Step 4

Simplify.

Step 4.1

Subtract $\frac{7}{t^{2}}$ from $\frac{7}{t^{2}}$ .

$\frac{0}{h}$

Step 4.2

Divide $0$ by $h$ .

$0$
