First, graph the equation (this curve will serve as the boundary)

Note: since there is an '=' sign in the inequality, this means that the boundary is a solid line

Graph of

Now pick a point that is NOT on the curve of . Let's pick the point (0,1). This means that we have the values and . Now plug them into the inequality:

Go back to the inequality

Plug in and

Square 0 to get 0

Since this inequality is true, this means that we shade the ENTIRE region that this point lies in. So just shade the region above the graph to get the following:

Graph of where the red line is the boundary equation (solid line) with the shaded region in green.
