Notes Key Operation Display Example 5 SHIFT/CHANGE ] ] ] ] S hift (Change the location of graphs) G raph shift function helps students grasp the relationship between an equation and its graph. Shift the graph’s location without changing its shape, and the change is immediately reflected in the equation on the right side of the display.
Notes Key Operation Display Example 6 When the graph of y = x 2 is changed, how does it affect the equation? C hange G raph change function helps students grasp the relationship between an equation and its graph. Change the shape of the graph, and the change is immediately reflected in the equation on the right side of the display.

10 G raphing P r ocedur es Following outlines graphing procedures and indicates the steps where Sharp's unique functions can be used to simplify operations.
Notes Key Operation Display Example 11 R apid graph Graphing has never been easier. With its full range of preset equations, rapid graph simplifies equation input. Use in conjunction with the rapid window function or with any graph created. Draw the graph for y = 2sin (-2x+ ) + 2 using the rapid graph function.
Notes Key Operation Display Example 12 R apid windo w Rapid window simplifies setting window size with a range of preset values. Use in con- junction with the rapid graph function or with any graph created. After using Rapid Graph to draw the graph of y = 2sin (-2x+ ) + 2 (refer p.
Notes Key Operation Display Example 13 R apid z oom Rapid zoom offers one-touch adjustment of window size while viewing the graph. No more guessing or wasting class time to find optimal values for window size. Adjust the viewing window for y = x 3 + x 2 - 2x to show the entire graph.
