Write the domain of the function in interval notation. $$f ( x ) = \sqrt [ 3 ] { x - 12 }$$
A) $[ 12 , \infty )$
B) $( 12 , \infty )$
C) $( - \infty , 12 ]$
D) $( - \infty , \infty )$

Question

Quizplus · Accepted Answer

The cube root function, $\sqrt[3]{x - 12}$, 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, $( - \infty , \infty )$.
