Thank you

Answer 14

What are the four x-values in (1, 0), (4, 2), (7, 4), (10, 6)?

Answer 15

1,4,7,10

Answer 16

Right. All the x-values are different, so this definitely is a function. Given an x-value, there is exactly one y value connected with it.

Now look at (5,-2),(5-1),(5,0),(5,1). What are the four x-values?

Answer 17

Thank you and 5,5,5,5 so im guessing its not a function since their all the same

Answer 18

That's right. If any x value has more than ONE y value associated with it, the relationship is NOT a function. It's important that you know how to spot a function and how to spot a nonfunction/

If you drew a circle and then drew a vertical line through the circle, how many times would that line intersect the circle?

Answer 19

2? im not quite sure

Answer 20

Right, 2. So for one x-value, you have how many y-value(s)?

Answer 21

Thats all the questions I have for those Are you willing to help with a different set of questions please.

Answer 22

and 2 y values to answer your question

Answer 23

So does the graph of the circle (relation) represent a function or not?

It is not a function
