Example 2 To use Auto Range to graph the following functions when the x-axis range is set as X min = -4 and X max ..= 6: y (x + 2)(x - 4) y = -(x + 2) (x - 4) y= 2x + 4 y = -2x - 4 Input the function to draw the graph.

In the GRAPH Mode, Auto Range is valid for all graphs drawn. •You cannot use Auto Range inside a program. •When Ant() Range is used inside of a multistatement formed using colons only, Auto Range parameters are applied throughout the multistatement, even in sections that do not contain graph functions. .When Auto Range is used in a statement that uses a display result command to draw a graph, Auto Range parameters are applied up to the display result command, but any graphs drawn after the display result command are drawn according to normal graph overdraw rules (page 159). -218- •Graph Adjust This function makes the x-range the same as the y-range. It is helpful when drawing circle graphs. This function is available from the second Zoom/Auto Range menu. O(Zoom)El(Q) IlWaITURPria Example To use -Graph Adjust to draw the graph for r = 5 sin O.
