Question

The vertex of the parabola below is at the point (1, 3), and the point (2, 6) is on the parabola. What is the equation of the parabola?

Answer 1

Easily we can use formula y=(x-h)^2 +k

as equation of a parabola if vertex was (h,k):

Y=(x-1)^2 + 3

and maybe node (2,6) is incorrect for this vertex of a parabola!!!
