$"Domain:"$ ${x in RR | x ne 13}$

We have: $f(x) = frac(8)(x - 13)$

The domain of this function is dependent on the denominator.

The denominator of any fraction cannot be equal to zero:

$Rightarrow x - 13 ne 0$

$therefore x ne 13$

Therefore, the domain of $f(x)$ is ${x in RR | x ne 13}$ .

What is the domain of f(x) = 8/(x-13)f(x) = 8/(x-13)?
