im going to try to make this as short and easy to follow as possible haha and im just warning, this is probably so simple that i cant even grasp it because im reading too deeply into it. okay, im working with these three points: [tex]A (0, 1) C (2, 6) D (3, 10)[/tex] i worked them into three equations, the first one is killing me though! [tex] a(0)^2 + b (0) + c = 1[/tex] this is the one im having trouble with, i cant set it up properly because all i have is [tex]c = 1[/tex] i have for the other two: [tex]C. . ., 4a + 2b +c = 6[/tex] [tex]D. . ., 9a + 3b + c = 10[/tex] now, in order to get my model for [tex]y = ax^2 + bx + c[/tex] how would i set this up, other than that im doing alright..
