Answer 2

The x-axis would be the horizontal axis.
V points to the origin.
Y points to the positive y-axis but I think Y is meant to point to the entire Y axis.

See what you think.

Answer 3

would it be U

Answer 4

U is the y-axis. We are naming the x-axis.

Answer 5

The only possible match for the x-axis that I see is Y.

Answer 6

so it would be Y because its pointing at the x axis isnt it

Answer 7

so it would be Y because its pointing at the x axis isnt it YES

Answer 8

Any set of ordered pairs is a relation.
For a relation to also be a function, no x value in the relation can be paired with the same y value for that x.

In the chart, each x is paired with a different y.

The relation is also a function.

Answer 9

so it would be both a function and a relation?

Answer 10

Correct.

Answer 11

The third set of ordered pairs are shown as a mapping. That is another way to show which x goes with which y.

It is a relation.

Look at the 6 in the drawing. 6 is paired with 0 AND also with 4.

That violates the function rule that a given x (6 in this case) cannot be paired with 2 different y values for that x (in this case, 0 and 4).

The mapping is not a function.

What did you get as the answer?
