the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. which graph represents a function?
Answer
Explanation:
Step1: Recall vertical - line test
A graph represents a function if any vertical line drawn on the graph intersects the graph at most once.
Step2: Analyze each graph
Check each of the given graphs for the vertical - line test. If a vertical line can be drawn such that it intersects the graph at more than one point, it is not a function.
Answer:
The graph that passes the vertical - line test (where no vertical line intersects the graph at more than one point) represents a function. Without seeing the specific details of each graph, in general, you need to apply the vertical - line test to determine which one is the function. If you describe the graphs in more detail (e.g., number of points, their positions), a more specific answer can be given.
