A technician is using a monitoring system to analyze signal patterns. On the coordinate display, two distinct patterns appear: a vertical parabola and a circle. Match each pattern with its correct classification regarding whether it represents a function, based on the vertical line test.

An urban planner is reviewing geometric models on a coordinate map. A circular boundary represents a park, while a vertical parabola represents the arc of a bridge. When applying the vertical line test to these models to determine if they are functions of $x$, which of the following statements is true?

Infrastructure Mapping and Function Analysis

A technician is modeling a circular sensor path on a coordinate grid. This circular path does not represent a function because a vertical line drawn through its interior intersects the graph at exactly ____ points.

A maintenance technician is using a coordinate grid to plot the arc of a support beam, which is shaped like a vertical parabola opening upward. True or False: This parabolic path represents a function because any vertical line drawn on the grid will intersect the graph at most one time.
