Question

The mapping diagram represents a relation where x represents the independent variable and y represents the dependent variable. Is the relation a function? Explain. Yes, because for each input there is exactly one output Yes, because for each output there is exactly one input No, because for each input there is not exactly one output No, because for each output there is not exactly one input

Answer 1

Answer:No

Explanation:

Because each X is an input, this means that Y is obviously the output.

In order for a set of data, there must ALWAYS be one output for every input, no more, no less. Because this particular set of data has multiple Y values with respect to different X values, this is not a function. Your correct answer is "No, because for each input there is not exactly one output."
