Using your Graphing Calculator:
To find the TURNING POINT
y= x2 + x ­ 6
1. Put the equation in y=
2. Press ZOOM 6
3. 2nd CALC, MAX or MIN
4. Left bound? ‐ move cursor to the left the curve
Right bound?‐ move the cursor to right of the curve
Guess?‐ move the cursor to the middle
x= y= *the x value is also your Axis of Symmetry
