Question
What is a real life application of a parabola? and show the graph.
Answer
The best example of a parabola is the headlight of a car. Though not readily appearant, any time there is a need for focusing of light, the reflecting lens behind it is a parabola. The light rays coming out from the center point all hit the sides and go out in the same direction. I do not have an example readily at hand for the example.
