Cubic Parent Function Table. The simplest cubic function or parent function is fx x 3 where a 1 and both h and k 0 as in fx1x - 0 3 0. You start graphing the cubic function parent graph at the origin 0 0.
Keep in mind that the square root function only utilizes the positive square root. Over the line y x. C is a real number OddEven.
The domain of quadratic cubic and cube root parent functions is all real numbers.
F x a x 3 b x 2 c x d. F x a x 3 b x 2 c x d. The cubic parent function g x x3 is shown in graph form in this figure. From 00 you graph 11 3 11 22 3 28 etc.
