What's the question?

anonymous · Answer

graph please

anonymous · Answer

Place values in x and y so that

when x = 0, y = ?
or when y = 0, x = ?

So that you can plot.

http://www.wolframalpha.com/input/?i=plot+y+%3D+%E2%80%932x%5E2+%2B+2+ (If the link doesn't work..) If you type "plot y = –2x^2 + 2 " into the question space, it will plot it for you to check your answers. +2 is the Y intercept. Then use Order's method of plug and chug for values of x and y.

y=-2x^2
when y = 0

0=-2x^2+2
0=-22x^2
x^2=1
x=1

(1,0)

When x=0

y=-2(0)^2+2
y=2

(0,2)

Those are the points on the graph of the first equation
