Answer by nyc_function(2741) (Show Source): You can put this solution on YOUR website!
From your equation, I can see that this is a quadratic equation becuase the biggest exponent is 2. Since the value in front of the x^2 term is negative, we have an upside down parabola.
I will make 4 points for you to graph on the xy-plane.
I will pick different values for x.
Let x = 0
y = -2(0)^2
y = 0
Our first point is (0,0).
Let x = 1
y = -2(1)^2
y = -2(1)
y = -2
Our second point is (1,-2).
Let x = -3
y = -2(-3)^2
y = -2(9)
y = -18
Our third point is (-3,-18).
How about one more point?
Let x = -4
y = -2(-4)^2
y = -2(16)
y = -32
Our fourth point is (-4,-32).

You have four points. Now, you can plot them on the xy-plane.
