*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x_v = \frac{-b}{2a}]


The *[tex \Large y]-coordinate of the vertex of a parabola in standard form:  *[tex \Large p(x)\ =\ ax^2\ +\ bx\ +\ c] is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y_v = p(x_v) = p\left(\frac{-b}{2a}\right)\ =\ a\left(\frac{-b}{2a}\right)^2\ +\ b\left(\frac{-b}{2a}\right)\ +\ c]
