Use the given graph. determine the period of the function.

Period of the function in the graph is:

   3

Step-by-step explanation:

Period of a function: If function value does not change when its argument is increased by a certain nonzero number,then that number is called the period of the function.

i.e.  f(t+x)=f(x) then t is called its period

We have to determine the period of the function in the graph.

Clearly f(x+3)=f(x) in the given graph

Hence, the period of the function is:

    3
