Graphing 'y is greater than or equal to x-squared'

Re: Graphing issue

to graph y is greater than or equal to x-squared

One approach...

if x = | 0 | 1 | 2 |-1 | -2 | etc.
y >/=| 0 | 1 | 4 |+1 | +4|

This gives the points (0,0), (1,1), (2,4), (-1,1), (-2,4),...

The points take care of the = portion. You can create more points and plot them, then shade in the portion of the graph that represents ">".
 
Another approach: y = x^2 is a parabola, vertex at the origin, opening upward.

Test a point not on the graph: (0, 1). 1 > 0^2, which is true. (0, 1) is inside the parabola, so the graph of y > x^2 is all points in the interior of the parabola.
