Question

How do I draw this out I am confused?

The bridge forms parabolic arch. The span of the arch is 60 m and its center is 10 m above either end.
(1) draw sketch of arch, include x and y axes where the vertex is at the origin.

Is 10 m the axis of symmetry? What does it mean by span of arch?

This should help

Answer 2

Thanks I understand the span..it says vertex is at the origin so it is (0,0( right? Then what is 10 m?

Answer 3

10m describes the height of the bridge from the ground
