The sign only changes when divided or multiplied by a negative number.
A quadratic function is a function of the form

. The
vertex,

of a quadratic function is determined by the formula:

and

; where

is the
x-coordinate of the vertex and

is the
y-coordinate of the vertex. The value of

determines if the <span>
parabola opens upward or downward; if</span>

is positive, the parabola<span> opens upward and the vertex is the
minimum value, but if </span>

is negative <span>the graph opens downward and the vertex is the
maximum value. Since the quadratic function only has one vertex, it </span><span>could not contain both a minimum vertex and a maximum vertex at the same time.</span>
