Graph of a Mathematical Function

The image displays a blue line forming a series of repeating, undulating curves against a dark background. This pattern strongly suggests the graph of a mathematical function, specifically one that is periodic or represents a wave form. A red horizontal line with arrows highlights a segment below one of the curves, likely indicating a specific interval, such as a period or a range along an axis. The overall illustration serves as a clear diagram for concepts found in mathematics or physics, like oscillation or signal analysis.
