Q

A quadratic function can be written in the form:

A

ax2+bx+c

where a, b, and c are constants with a ≠ 0.

2
Q

The x coordinate of the vertex of the graph of y=ax2+bx+c is given by:

A

x=-(b/2a)

To find the y coordinate, substitute the x value of the vertex into the equation.

3
Q

The vertex form of the equation of a parabola with vertex ( h, k) is:

A

y=a(x-h)2+k

Where a ≠ 0 is a constant. If a > 0,the parabola opens upward; if a < 0, then the parabola opens downward.
