which graph does not show a function?
which graph does not show a function?
Answer
Explanation:
Step1: Recall the vertical line test
A graph represents a function if and only if every vertical line intersects the graph at most once.
Step2: Analyze each graph
For the first graph (top - left), when we consider the concept of the vertical line test, we can see that there are vertical lines that will intersect the graph more than once. For example, if we draw a vertical line in the region where the horizontal segments are stacked vertically. For the other three graphs (top - right, bottom - left, bottom - right), every vertical line will intersect the graph at most once.
Answer:
The top - left graph does not show a function.
