Question 50686
<pre><font size = 4 color = "dark maroon"><b>How do you use a graphing calculator to graph the following equation:
x2-11x+18. I am assuming by X2 it means x to the second power.

I assume you have a TI-82, 83 or 84.

If so,

1.  Press the " Y= " key

 If anything is listed after Y1= (or after Y2= or any of the Y's),
 then press "CLEAR" to get rid of it

2.  After Y1= type X²-11X+10

To type the exponent " ² ", use the " <i>x</i>² " key.

3. Press the " WINDOW " key

After Xmin= type -10
After Xmax= type 20
After Xscl= type 5
After Ymin= type -25
After Ymax= type 20
After Yscl= type 5
(Leave the resolution set at 1, if your TI has this)

4. Press the " GRAPH " key

If this doesn't work, then something else need to be cleared.
Post again or email me.
