Then the vertex is (3/2, 25/2)
A general equation of a parabola is:
[tex]y=ax^2\text{ + bx + c; the vertex of a parabola is the point (h,k) where h = -b/2a}[/tex]
This way you find the value of h
Since h is a value of x, you can find the corresponing value of y by using the original equation:
[tex]y=ah^2\text{ + bh + c}[/tex]
and this will be the value of K
