PLEASE HELP THIS IS IMPORTANT DONT TROLL ME PLZ
While exploring a volcano, Zane heard some rumbling, so he decided to climb up out of there as quickly as he could.
Zane's elevation relative to the edge of the inside of the volcano (in meters) as a function of time (in seconds) is graphed.
How high did Zane climb every 7 seconds?
