Explain, using the theorems, why the function is continuous at every number in its domain. Vx - 5 Q(x) = x3 - 5 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 State the domain. (Enter your answer using interval notation.)
