Writing Objectively - 2. Tables Exit Slip 4/20/10

The results of my 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 x. The scale of these values: -25 to 25 it was chosen randomly, first. 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 cubic function , I notice as the x-values increase the y-values decrease, from 0 to -25. And from 5- 25 as the x-values increase the y-value increase.

Since y2 is a cubic function y-values for y2=7x^3+100 are shown in the third column of table 1. The y-value first decrease as x-value increase from 0 to -25, then from 5 to 25 the x-value increase and the y-value increase.
