Height of the top of your head as you bounce on a pogo stick

The "n" and "U" should be drawn as curved lines (I'm drawing using the keys available to me but if this were hand-drawn the graph would be more ~ -curvy/wavy looking)

The Y-axis "Height in Feet": shows the height of their head from the ground in feet as they bounce
The X-axis "Length of Passing Time in Seconds": shows the seconds as they pass while jumping on the pogo stick
The assumption being made: The head isn't starting from 0 feet off the ground so we began the line near the 5-foot mark
Remember to label your x and y axises
