$f (x) = \frac{x^{2} - 36}{x + 6}$ at $x = - 6$

Step 1

Replace the variable $x$ with $- 6$ in the expression.

$f (- 6) = \frac{{(- 6)}^{2} - 36}{(- 6) + 6}$

Step 2

Add $- 6$ and $6$ .

$f (- 6) = \frac{{(- 6)}^{2} - 36}{0}$

Step 3

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