How would I go about solving this equation algebraically?
Find the equation of the parabola
y=ax^2 + bx+c
that passes through the given points.
(2,0) (3,1) (4,0)
Thanks.

Sketch a graph.
see that vertex is at (3.1)
so form is
(y+1) = k(x3)^2
substitute in (2,0) to find k
1 = k (1)^2
k = 1
so
y = (x3)^2
or
y = x^2  6 x + 9

I plugged that into my graphing calculator and that isn't right. Could someone help?
