The results of calculation from the two function are shown in Table 1, and the graph shown in Figure 1.The first function is y1=4x^3 and the second function is y2=7x^3
The first column contains some values for the independent variable x.The domain of these values for the independent variables x.The domain of these values -25 to positive 25 was chosen randomly at first. I wanted the important part of the graph to show. Some examples are in the vertex,the root,the local min.,the local max. and the scale being set to 1.


The x values were substituted into the function y1 and the results are displayed in the second column.

Since y1 is a quadratic function the y values first decrease as x values increased from negative number to zero.(0,0) is the graph. Then the y value increases while x increases from 0 to positive values.

The y values for y2 7x^3 shown in the third column of table one. The y value increases as x values but only until x-0 since this is also a quadratic function the y values decreases past (0,0).
