Graphing Cube Root Functions

Overview

Goal. Graph a cube root function from its center point, evaluate it at perfect cubes including negative ones, and state its domain and range.

Cube root function (definition). A function that contains a cube root of the variable, like f(x) = the cube root of x.

The parent cube root function: negative inputs, all-real domain and range, and the same shift rules.
