Exit slip 4/19

The results of calculations from the two functions are shown in table 1. The first function is y1=4x^3+5 and the second function is y2=7x^3+100.

The first column contains some values for the independent variable x. The domain of these values: -25 to 25 was chosen randomly, first. I just wanted to make surer the important points of the graph would show. Some examples of the important points are: vertex, the roots, the local minimum, the local maximum, etc. The scale is set to 5.

The x values were substituted into the function, y1, and the results are displayed in the second column. Since y1 is a third degree polynomial. The y-values first increase as x-values increase from negative numbers to positive numbers. There is no vertex because this is a third degree polynoial.

The y-values for y2=7x^3+100 are shown in the third column of the table 1. The y-values increase as x-values increase.
