u To calculate the root of a graph
1. Draw a graph.
2. Press !5(G-SOLVE)1(ROOT).
3. If there are multiple graphs on the graph screen, one of them will start flashing. Use f and
c to move the flashing to the graph you want to analyze.
4. To select the flashing graph, press w. This displays the value produced by the analysis.
Example Graph the function shown below, and then calculate the roots.
Y1 =
x

− 4x
• When an analysis produces multiple values, press e to calculate the next value. Pressing
d returns to the previous value.
• When “On” is selected for the Derivative setting on the Setup screen, the derivative will
be displayed along with the root when you calculate the root of a graph using the above
procedure.
u To calculate the point of intersection of two graphs
1. Draw the graphs.
2. Press !5(G-SOLVE)5(INTSECT). If there are three or more graphs on the graph
screen, one of them will start flashing.
3. Use f and c to move the flashing to one of the graphs whose point of intersection you
want to determine and then press w.
4. Use f and c to move the flashing to the other graph whose point of intersection you
want to determine and then press w.
5. Press w to determine the point of intersection for the two graphs.
When an analysis produces multiple values, press e to calculate the next value.
Pressing d returns to the previous value.
