What is the period of the function shown in the graph?
How far does it go in the x direction before it starts repeating? That is the period.
Tell me what you think it is and i. or someone else, will tell you if you are right.
I think it's either 2 or 3?
One point is (0,0), And from that point the curve goes up.
At what next point does this happen?
I mean what is the x value when is the y value next at 0 with the curve on its way up,
Would that be 4?
Yes it would be 4 and that is the period.
