What is the equation, in standard form, of a parabola that contains the following points?
(–2, –22.5), (0, – 1.5), (4, – 67.5)
y = 4.5x2 – 1.5x + 1.5
y = 1.5x2 – 4.5x – 1.5
y = 4.5x2 + 1.5x – 1.5
y = 1.5x2 + 1.5x +4.5

So you have three unknowns, but you are given three conditions: \[\Large f(2)=22.5 \\ \Large f(0)=1.5 \\ \Large f(4)=67.5\]
