1.Mathematical definition
PARABOLA-the set of all points the equidistant from a point called the focus and a line called the directrix.(Mrs. Kirch)
2.Mathematical equation-(x-h)^2=4p(y-k) and (y-k)^2=4p(x-h)
Graphically
x-h
The directrix is the line that crosses the vertex.the focus located on the directrix line.
3. This picture shows how parabolas are are used in real life.they are mathematically calculated to be kept standing and to support a roof. Its interesting how a simple shape can cause the building to stand.
Parabolas are seen in buildings and bridges. It requires equations that help the engineer built a stable building or bridge. For bridges it must be calculated to be strong enough to hold cars.
