Graph the parabola y+=+x%5E2-8

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+0%2Cx%5E2-8%29+

Make this boundary line a solid line. Then shade above this boundary curve to complete the graph of y%3E=x%5E2-8. The shaded region is in blue. The boundary line (somewhat hidden) is in green.

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+0%2Cx%5E2-8%2Cy%3E=x%5E2-8%29+

we shade above because of the ">" sign (and because y is isolated)
