Example: Determining if a Graphed Straight Line and a Horizontal Parabola Represent a Function Using the Vertical Line Test

Example: Determining if a Graphed Vertical Parabola and a Circle Represent a Function Using the Vertical Line Test

Example: Determining if a Graphed Ellipse and a Slanted Line Represent a Function Using the Vertical Line Test

Example: Verifying the Graph of the Equation $y = 2x - 3$ is a Function

A data analyst is reviewing a graph that tracks a machine's power consumption over a 24-hour period. To verify if the consumption is a mathematical function of time, the analyst applies the vertical line test. According to this test, the analyst should conclude the graph does not represent a function if which of the following occurs?

A laboratory technician is analyzing a graph that represents the reaction rate of a chemical compound over various temperatures. To determine if the reaction rate is a mathematical function of the temperature, the technician applies the vertical line test. Match each observation from the test with the correct conclusion about the relationship shown on the graph.

An operations manager is using a graph to track the relationship between factory output and energy consumption. True or False: According to the Vertical Line Test, this graph represents a mathematical function if every vertical line drawn on the coordinate plane intersects the graph at most once.

Interpreting Sensor Data with the Vertical Line Test

A business analyst is reviewing a chart mapping daily marketing spend to sales revenue. To visually confirm whether the graph represents a mathematical function, the analyst applies the vertical line test. For the graph to pass this test and be considered a function, any vertical line drawn on the coordinate plane must intersect the graph at a maximum of ____ point(s).
