These are two calculations from the two functions; this is shown in Table 1 and Figure 1. The first function is y1=4x^3 and the second function is y2=7x^3.
The first column has some values for the independent variable x. The value for x ranges from -25 to 25. This was chosen at random. The scale is set to 5, so all the important points of the graph would be shown.
These x values were plug into the function y1 and the results are shown in the second column. The y-values first decrease as x-values increase from negative numbers to zero. (0,0) is the vertex and it's also the minimum of the graph. Then, the y-values increase as x increase from 0 to positive values.
The y-values for y2=7x^3 are shown in the third column of table 1. The y-values decreases but only until x=0. Then after that x is 0 the graph increases.
