Answer:
(0,3) and (π,3)
Explanation:
The period of a sine graph is the magnitude of the interval over which the graph completes a full cycle.
From the graph, the sine function completed one full cycle in [0,π]
The period is π.
The midline us y=3.
Two points on the midline that are separated by a distance of π are (0,3) and (π,3)
