Math Problem Statement
An arch in a memorial park, having a parabolic shape, has a base width of 28 feet and opens downward with the vertex at the origin. Suppose the base serves as its latus rectum. Find the equation (in standard form) that models this shape, then graph it. State the focus, directrix, and axis of symmetry.
