You posted this already and were given a method to do it by fitting a parabola of form ax^2 + bx + c. I left you with a proof that c = 1, and two additional equations to solve
-2 = 4a - 2b +1, and
2 = a + b + 1
(I had one of the equations wrong)
If you finish the problem, you should get
y = (-1/6)x^2 + (7/6)x +1
I need a function rule for the following:
X Y
-2 -2
0 1
1 3

This does not help me at all. I am only in the beginning of Algebra 1. I have had nothing yet about parabola or the symbols you use. I just need a function rule for a graph!!!
where can find a site that helps with math
