Explain, using the theorems, why the function is continuous at every number in its domain.

$Q(x)=\frac{\sqrt[3]{x-5}}{x^3-5}$

$Q(x)$ is a polynomial, so it is continuous at every number in its domain.

$Q(x)$ is a rational function, so it is continuous at every number in its domain.

$Q(x)$ is built up from functions that are continuous for all real numbers, so it is continuous at every number in its doma $Q(x)$ is not continuous at every number in its domain.

none of these

tate the domain. $($Enter your answer using interval notation.$)$
