Hi! I'm stuck on this problem. Can someone help please?

Highway engineers design a parabolic curve for an entrance ramp from a straight street to an interstate highway (see figure 64 on page 742 of your textbook). The vertex of the curve passes through (0, 0) and the parabola passes through (1000, + 800). Find an equation for the parabola.

y = ax^2

800 = a * 1000^2

a = 800/1000^2

y = 800/1000^2  x^2
