For any quadratic of the form

, the graph is a parabola with a vertical line axis of symmetry opening upward if

or downward if

.

The

-coordinate of the vertex is given by

. The

-coordinate of the vertex is

The axis of symmetry is the line with the equation

The

-intercept is the point

Symmetry demands that there is a point on the graph at

The

-intercepts, if they exist (and they do exist for your problem) are at

and

where

and

are the zeros of the polynomial. In other words,

and

. Note that your trinomial factors neatly over the integers: -3 + 2 = -1 and -3 X 2 = -6.

Plot the above five points and draw a smooth curve.

For future reference, any quadratic with a non-zero value for the constant term and the constant and lead coefficient have opposite signs, you are guaranteed two distinct real number zeros.
