Cubic Function Graph Examples. This practice further works students skills with graphing and increases familiarity with function notation. Example 2 f is a cubic function given by f x - x - 2 3.
This is the graph of the equation 2x 3 0x 2 0x0. -6-2 is one of the points this function passes through. This simplifies to y 2x 3.
Similarly the volume of a cube as a function of the length of.
The diagram below shows the graph of the cubic function kx x3 k x x 3. Since the cube root of -8 is -2 you can conclude that when x-6 y-2 and you know that the point -6-2 is on the graph of this cubic function. This is the graph of the equation 2x 3 0x 2 0x0. A the value of y when x 25.
