Do you know what are parabola is? Do you know what it looks like? If you want to  know what it is, watch the video and read the text at the bottom.

A parabola is a line on the graph that curves. Sometimes it looks like a rainbow, other times it looks like a smiley face. The two different kind of parabola is minimum and maximum. You can tell the difference between them easily when you compare them to smiley faces. The maximum always has a sad face and the minimum always has a happy face. Parabolas are mostly used in math, but you can see them everywhere. You may be confused, but look around you. You see anything that was an arc? Here are some simple examples: banana, water fountain, airplane taking off and landing, roller coaster, the McDonald’s ‘m’ letter, diving from a diving board, throwing a ball, a horse jumping over a fence, a ball bouncing, and so on. There are so many other parabolas around you and you don’t realize it.

In the video, I include a graph of the parabola. The parabola was formed by a paper ball being thrown in the air. The graph in the video shows you an example of restricted graph. It is restricted to the domain and range. This means that when it is restricted to the domain, it is the time when I threw the paper ball to the time it touches the ground. The restricted on the range is when it goes to the lowest point to the highest point, the vertex.

So far in math, we have been learning Quadratic Equations and finding other examples in real life that have a parabola. From seeing the video above and this text, I hope that you know realize that parabola is all around you.
