$h (- 3) = \frac{\sqrt{x + 12} - 3}{x + 3}$

Step 1

Replace the variable $x$ with $- 3$ in the expression.

$h (- 3) = \frac{\sqrt{(- 3) + 12} - 3}{(- 3) + 3}$

Step 2

Add $- 3$ and $3$ .

$h (- 3) = \frac{\sqrt{(- 3) + 12} - 3}{0}$

Step 3

The expression contains a division by $0$ . The expression is undefined.
