Answer

Explanation:

Step1: Recall period definition

The period of a periodic - function is the interval after which the function repeats its values.

Step2: Analyze the graph

The graph shows the monthly rainfall totals for a two - year period. The pattern of rainfall repeats every 12 months. For example, the rainfall amounts for February of the first year and February of the second year follow a similar pattern, as do the other months. This indicates that the function representing the rainfall has a period of 12 months.

Answer:

12 months
