Quizplus · Accepted Answer

The cube root function, $\sqrt[3]{x-18}$, is defined for all real numbers because you can take the cube root of any real number, including negatives, zero, and positives. Therefore, the domain is all real numbers, $(-\infty, \infty)$.

Find the Domain of the Function f(x)=x−183f(x)=\sqrt[3]{x-18}f(x)=3x−18​ A) (−∞,18)(-\infty, 18)(−∞,18) B) [18,∞)[18, \infty)[18,∞)
