Answer
domain : $\{\ x \ |\ \ x\neq 8 \ \}$
interval notation: $(-\infty,8)\cup(8,\infty)$
Work Step by Step
See example 1.
Division by 0 is undefined, so
f(x) will be defined for all real numbers except for
the number(s) x that yield zero in the denominator:
$x-8=0$
$x=8$
domain : $\{\ x \ |\ \ x\neq 8 \ \}$
interval notation: $(-\infty,8)\cup(8,\infty)$
