Question 1 of 10

2. Is the following a function? Explain why or why not.

A.Yes, this does represent a function, because all the points are distinct (none of them are coincident.

B.No, this does not represent a function, since a function can not be made up of only points.

C.No, this does not represent a function, since it fails the vertical line test.

D.No, this does not represent a function, since a function is made up of many more points.
