------------------------------------
y = (-1/2)x^2
-------
Plot points and draw a smooth curve thru them:
Let x = -2, then y = (-1/2)(-2)^2 = -2
Let x = -1 , then y = (-1/2)(-1)^2 = -1/2
Let x = 0 , then y = (-1/2)(0)^2 = 0
Let x = 1 , then y = (-1/2)(1)^2 = -1/2
Let x = 2 , then y = (-1/2)(2)^2 = -2
==========================================
So you have points (-2,-2)(-1,-1/2)(0,0)(1,-1/2)(2,-2)

==========================================
