A parabola has a vertex at (-1.5,12.5) and passes through (0,8). Solve for "a" and write the equation in vertex form.
Formula: f(x) = a(x - h)2 + k
y = -1.5(12.5 - 8)2
y = 2(x + 0)2 + 8
y = -2(x + 1.5)2 + 12.5
y = 8(x + 1.5)2 - 12.5
None of the above

Use the vertex form to write the equation of the parabola.
y = -(x - 2)2 + 5
y = -3(x - 2)2 + 5
y = -3(x + 2)2 + 5
y = -3(x + 2)2 - 5
