Can someone help me with quadratic graphing?

[Ender]

I have no idea how to graph a simple quadratic function on my TI-86

Can someone help me out? I've looked on some mIRC channels and in my manual, but I can't seem to find it...

Anyone?

Can't you just plug in x^2 as a y= and hit graph?

Make sure you're working in radians, not degrees (at least, my old TI81 couldn't handle that stuff in degrees).
y=Ax^2+Bx+C

Push the GRAPH button, then F1 to select y(x)=, then enter your function in the y1= space, (for example 2x^2), then push 2nd then F5 to graph it.
