    What Is the Equation of a Parabola for a Bridge Needing Specific Dimensions?

    I thought that if the vertex was at the origin (0,0) that the equation would be y=axsquared, because the vertex is (h,k). I keep getting an extremely small number for k, which wouldn't work because then the width at that point would be way too small.
