Since in each option, each input is mapped to only one output, all the options are correct.

When a relationship represents a function?

A relationship represents a function when each input is mapped to only one output.

In this problem:

• For the Venn sets, only one line departs each value of x, hence it is a function.

• For the ordered pairs, each value of x(2, 5 and -4), is mapped to only one value of y, hence it is a function.

• The graph has no vertically aligned points, hence it is a function.

Thus all the options are correct.
