Answer:
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
