The graph of is shown as a dashed curve at right. Estimate the equations of the two other parabolas.

Notice the location of each vertex.

Notice that one is vertically stretched and the other one is inverted and vertically compressed.

Dashed upward parabola, vertex at origin, Solid upward parabola, skinner than dashed one, vertex at (5, comma 2). Downward parabola, consisting of open circles, with vertex at (5, comma 2), and wider than either upward parabola.
