Answer:
The graph of a quadratic function is a U-shaped curve called a parabola.
The sign on the coefficient
a
of the quadratic function affects whether the graph opens up or down. If
a
<
0
, the graph makes a frown (opens down) and if
a
>
0
then the graph makes a smile (opens up).
The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex.
The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.
