Today we learned about parabolas. A parabola is a set of points (x,y) that are equidistant from a fixed line (directrix) and a fixed point not on the line (focus). There are two equations you need to do and they correspond with which way the parabola is facing and opens up.
When a parabola is vertical it is equal to (x-h)^2 = 4p(y-k).
When a parabola is horizontal it is equal to (y-k)^2 = 4p(h-k).
P = the distance between the vertex and the focus = the distance between the vertex and the directrix
Find P with the coefficient of the equation equal to 4p.
Here's an example!
