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

Answer:
[tex]Period=3[/tex]
Step-by-step explanation:
we know that
The period of a periodic function is the interval of x-values on which the cycle of the graph that's repeated in both directions lies.
so
see the attached figure to better understand the problem
To calculate the period subtract [tex]1.5[/tex] from [tex]4.5[/tex]
[tex]Period=4.5-1.5=3[/tex]
