Remember that you can not take a square root of a negative number, so 'x^2' can not be greater than one. Since sqrt(-1) is imaginery, you can not have less than negative one.

Graph: y+=+3+-+3x%5E2 but stop at the x-axis ~~~> the vertex and the x-intercepts are the same (the points are not exact as the original equation)
