In order to find an intersection point, first **graph two functions**.
For this example, let
and * *.
The graphs of the functions in a **standard window **are shown below.

The intersection point of the two lines is not visible using a
standard window. **Zoom out **once
so that the intersection point is visible. (Remember to press **ENTER
**for the **zoom out **to happen). Now press **2nd **and
then **TRACE [Calc]** to get the **CALCULATE **menu.
Select **5:intersect. **

If the cursor is not near the intersection point, move it close to the point
of intersection using the **ARROW **keys, then press **ENTER**.

When **Second curve? **appears, press **ENTER** again.
When **Guess? ** appears, press **ENTER** once more.

The final screen shows that the intersection point is **(7,11)**. If there are
more points of intersection, move the cursor near each one and repeat the process.
