Question

what is the period of the graph below?
options: 0.5, 1, 2, 3

Explanation:

Step1: Identify peak positions

Locate consecutive peaks: e.g., at $x=0$ and $x=3$.

Step2: Calculate period difference

Subtract the two x-values: $3 - 0 = 3$.
Verify with other peaks (e.g., $x=3$ to $x=6$: $6-3=3$) to confirm consistency.
