Question

is this a possible graph of periodic phenomena? (1 point) yes, because most of the graph lies above the x - axis. yes, because the graph appears to have a cycle that repeats at regular intervals. no, because some points on the graph have negative values of y - coordinates. no, because the graph is a smooth curve rather than being comprised of line segments.

Explanation:

To determine if a graph represents periodic phenomena, we check if it has a repeating cycle at regular intervals. The first option is incorrect as the position relative to the x - axis (above or below) doesn't define periodicity. The third option is wrong because negative y - coordinates don't prevent periodicity. The fourth option is incorrect as the graph being a smooth curve (not line segments) doesn't disqualify it from being periodic. The second option is correct because the graph shows a cycle that repeats regularly.

Answer:

B. Yes, because the graph appears to have a cycle that repeats at regular intervals.
