Function Analysis

Example

Graph the two functions shown below and then determine the y-

 

coordinate for x = 0.5 and the x-coordinate for y = 2.2 on graph Y2.

 

Y1 = x + 1, Y2 = x(x + 2)(x – 2)

Use the following V-Window settings.

Xmin = –6.3, Xmax = 6.3, Xscale = 1

Ymin = –3.1, Ymax = 3.1, Yscale = 1 (initial defaults)

Result Screen

#When there are multiple results for the above procedure, press e to calculate the next value. Pressing d returns to the previous value.

#Step 3 of the above procedure is skipped when there is only one graph on the display.

#The X-CAL value cannot be obtained for a parametric function graph.

#After obtaining coordinates with the above procedure, you can input different coordinates by first pressing v.
