Using the appropriate theorems, explain why the function is continuous at every number in its domain. √√x-9 Q(x) = x3-9 O Q(x) is a polynomial, so it is continuous at every number in its domain. O Q(x) is a rational function, so it is continuous at every number in its domain. O Q(x) is built up from functions that are continuous for all real numbers, so it is continuous at every number in its domain. O Q(x) is not continuous at every number in its domain. O none of these Find the domain. (Enter your answer using interval notation.)
