On the same screen, graph y2 for h = 1, h 0.5, 0.3, and 0.1. Then, in a new window, try h = -1, - 0.5, and - 0.3. What happens as h-+0 ? Ash-+0 ? What phenomenon is being illustrated here? ecti 0/06 As h->07, the graph of y, begins to resemble the graph of the function y = 9/pg ( lype an expression using x as the variable.) 690 Unlin What
