Okay, well I need a little help understanding this.
Apparently from my homework I am given a parabola with 3 points, (0,0),(2,-2), and (3,4). I just need help understanding how to figure out the equation in standard form (y=ax^2+bx+c).
So far all I have is:
-2=a(1)^2+b(1)+c -> -2 = a+b+c
-2=a(2)^2+b(2)+c -> -2 = 4a+2b+c
4=a(3)^2+b(3)+c -> 4 =9a+3b+c
All I really have to do is figure out what a,b, and c are and I can figure out the rest.
Also, can you help explain how you came across doing it?
