A parabolic arch supports a bridge. The arch is 200 m wide at its base and 4 m tall in the middle.
a) Show this information on a graph by placing the vertex on the y-axis so that the x-axis represents the base of the arch
-------------------------------------------------------------------------
Vertex (0,4);
Horizontal Axis Intercepts (0,-100) and (0,100).
The vertex will indicate a standard form like ;
and the zeros indicate something like .
