In my Algebra class we are doing parabola's. I get how to do them but i want to get extra help to make it even easier and less thoughtful to do when a test or the ECA comes.

All parabolas are āUā shaped and they will have a highest or lowest point that is called the vertex.  Parabolas may open up or down and may or may not have x-intercepts and they will always have a single y-intercept.

Note as well that a parabola that opens down will always open down and a parabola that opens up will always open up.  In other words a parabola will not all of a sudden turn around and start opening up if it has already started opening down.  Similarly, if it has already started opening up it will not turn around and start opening down all of a sudden.

The center line with each of these parabolas is called the axis of symmetry.  Every parabola has an axis of symmetry and, as the graph shows, the graph to either side of the axis of symmetry is a mirror image of the other side.  This means that if we know a point on one side of the parabola we will also know a point on the other side based on the axis of symmetry.

Note that Vertex is at center of the directix and latus rectum .

we can understand how to solve the parabola problem using some practice problems
