Using the function concept, it is found that Graph 1 does not pass the vertical line test.
-----------------------
- In a function, each value of the input can only be mapped to one respective output value.
- If it is mapped to more than one value, it is not a function.
- In a graph, passing a vertical line, if it crosses the function in more than one point, a value of the input x has more than one corresponding output, and thus, is not a function.
- The image appended in the end shows that graph 1 does not pass the vertical line test.
