A Dolphin's Jump
Dolphins can jump from 15 to 30 feet igh and 10 to 15 feet wide. So the vertex would be (0,25). The y-intercept would also be (0,25). The water is the x-axis. Some scientists believe dolphins jump out of the water to save energy when traveling because moving through air is faster and easier than moving through water. Others think it is so dolphins can see food that is farther away. Another belief is that they jump to communicate and find mates. Some people even think it’s a way to clean themselves. But my favorite explanation is that they do it just for fun and good play.

Dolphins don’t only jump (I know this is about parabolas but I decided to give some more information about dolphins in general), the use a special call to speak. The whistle and squawk. They are very intelligent, some say they may be smarter than humans.
