Question

Does this image have a set of inputs to a set of possible outputs where each input is related to exactly one outputs Yes or No?

Explain your answer

Answer 1

Answer: Yes

This graph passes the vertical line test. This is a test where we try to draw a single vertical line through more than one point on the curve. In this case, such a thing is not possible. Any input x leads to exactly one output y. This graph is a function.
