is the line up or down for graphing y = –2x² + 2
1) this is a quadratic and cannot be a "line". It is a "curve"

thats what i mean sorry is the curve up or down
2) we then check the coefficient of the highest power of "x"
i put it as down but im not sure
it will first increase from -infinity, then reach a maximum and then decrease
okay i get that
so does it look like this then
|dw:1364413141919:dw|
sorry i couldn't draw it
looks like this. I cannot see your picture.
oh sorry it was a pic that looked like the one you drew except the curve was under the x axis is that correct?
yep. So, it first increases and then decreases. did you study derivatives?
yes and thank you :)
curve is under the x axis and downward.. at x = 0 it peak
at y =0 you can find x value and at x= 0 find value of y...
if you had studied derivatives, this becomes way easier
just a little bit and thank you again all for helping
