Which triangle has the highest rate of change? Even though the graph isn't a straight line, is it still a function? Explain why its still a function or why not.

#. Triangle 3 has the heighest rate of change because it has the largest height of all three triangle with same base.
#.Yes, the graph is still a fuction.
#. It is still a fuction because any vertical lines which passes through graph will cut it at only one point. Hence it passes the vertical line test.
