The graph shows the cube root parent function.Which statement best describes the function?A.The function is positive when x < 0 and when x > 0.B.The function is positive when x > 0.C.The function is positive when x < 0.D.The function is always positive.SUBMITarrow_backPREVIOUS
Solution
The cube root function, y = ∛x, is a function that is positive when x > 0 and negative when x < 0. This is because the cube root of a positive number is positive and the cube root of a negative number is negative. Therefore, the statement that best describes the function is A. The function is positive when x < 0 and when x > 0.
