Conic Sections- Parabola

1) A parabola is ant point on a parabola that is at an equal distance from the focus and the vertex, and the vertex and the directrix. Also, at any point on the parabola, you can move it around the focus in a way that it creates a parabola shape.

2) The focus affects the shape of the parabola in the way that wherever the focus is, that is where the parabola will form around. Also, p, which is the distance from the vertex and the focus and the focus and the directrix, if it is positive or negative, the graph will go either up, down, left, or right, depending on what term is squared.

3) These properties affect real life with dishes that are like satellites at a certain museum.One speaks in what is the focus and the sound waves hit the dish at the right angle to travel to the other dish and hits the focus for someone else to hear.
