7-30.

A parabola has vertex (2, 3) and contains the point (0, 0). Write an equation for this parabola. Homework Help ✎

For a vertically-oriented parabola, use the equation *y* = *a*(*x* − *h*)^{2} + *k* where (*h*, *k*) = (2, 3) and (*x*, *y*) = (0, 0).

For a "sleeping parabola" use the equation *x* = *a*(*y* − *k*)^{2} + *h*.

0 = *a*(0 − 2)^{2} + 3

−3 = *a*(4)
