how do you graph ?
Let x be -3, then
So plot the point (-3,.016)
Let x be -2, then
So plot the point (-2,.08)
Let x be -1, then
So plot the point (-1,.4)
Let x be 0, then
So plot the point (0,-2)
Let x be 1, then
So plot the point (1,-10)
Let x be 2, then
So we would plot the point (2,-50) if we
had big enough graph.
Draw a smooth line through those points and
it will look like this:
