instructions
$k(x)=\frac{x - 3}{x + 6}$

Explanation:

Step1: Identify non - valid x values

Set the denominator equal to zero: $x + 6=0$. Solving for $x$ gives $x=-6$. Division by zero is undefined.

Step2: Write domain in interval notation

All real numbers except $x = - 6$ can be used. In interval notation, this is $(-\infty,-6)\cup(-6,\infty)$.

Answer:

$(-\infty,-6)\cup(-6,\infty)$
