Graph the parabola y₁ = 1 - x² and the semicircle on the window [-1, 1] by [0, 1]. (You may want to adjust the window to make the semicircle look more like a semicircle.) Use TRACE to determine which is the “inside”curve (the parabola or the semicircle) and which is the “outside” curve. These graphs show that when you graph a parabola, you should draw the curve near the vertex to be slightly more “pointed” than a circular curve.
