Tell whether each graph is a function and justify your answer. Which graph is not a good representation of a real-world situation? Explain

To determine whether a graph represents a function, you can use the vertical line test. If a vertical line drawn through the graph intersects it at more than one point, then it is not a function.

1. Graph A: If it passes the vertical line test, it is a function.
2. Graph B: If it fails the vertical line test, it is not a function.

To identify which graph is not a good representation of a real-world situation:

– Consider whether the relationship depicted is realistic or if it has any variables that don’t make sense in a real context. For example, if a graph shows an impossible scenario, it cannot realistically represent a situation in the real world.

Please refer to your specific graphs and apply the test. If you need further help analyzing a particular graph, let me know!
