Both Classic Mode and MathPrint Mode
1. To find the yintercept: 

2. To find the xintercept:
Hit 2^{nd} TRACE button, #2 ZERO (called the "Root Key") allows you to find the xintercept(s). When asked for the Left Bound, move the cursor to the left of the intercept. Hitting ENTER will place a marker on the screen. For the Right Bound, move to the right of the intercept. Hit ENTER twice. 




3. To
find where the graphs intersect: Hit 2^{nd} TRACE button, #5 INTERSECT. When asked for the First Curve, move the cursor near the point of intersection you wish to find. Simply hit ENTER three times. 




4. To find a specific
value while tracing:
When tracing a graph, you may not be able to find the specific value that you desire by moving the arrow keys. To find your specific value while tracing, simply type the xvalue that you are looking for and hit ENTER. The cursor will automatically move to that point and yield the yvalue, if the xvalue is within the viewing window. If your needed xvalue is outside of the viewing window, adjust the window as to contain the needed xvalue.


5. To enter multiple graphs
