Find all numbers that are not in the domain of the function. Then give the domain using set notation.
-$f(x)=\frac{x-3}{8}$
A) $8 ;\{x \mid x \neq 8\}$
B) $0 ;\{x \mid x \neq 0\}$
C) $3 ;\{x \mid x \neq 3\}$
D) none; $(-\infty, \infty)$

The function $f(x)=\frac{x-3}{8}$ is defined for all real numbers because there are no values of $x$ that make the denominator zero or result in an undefined expression. Therefore, the domain is all real numbers, $(-\infty, \infty)$.
