C. function only

D. both a relation and a function

PLEASE ANSWER WITH A B C or D only thank you

Answer 1

"A B C or D only"? You're saying you don't actually want to learn ths material??

Answer 2

Im tired i have done them already, and i still need to do calc later -_-

Answer 3

Understand me ...please

Answer 4

Sorry, I don't help cheaters. And I don't believe you've done them because the other one you said you'd done you didn't know the answer and were just guessing.

Answer 5

Ok w/e i dont win anything by not saying stuff that isnt the truth

Answer 6

i got no reason to lie so -_-

Answer 7

What answer did you get for this one, then, and why?

Answer 8

I think they are a relation because they match

Answer 9

in some coordinates...

Answer 10

What do you mean by "they match"? Remember, as I've said with your last few questions, a relation is a function if each X value has a unique Y value. does that hold in this example?

Answer 11

But isnt this different ? Im responding with the answers that i have got to

Answer 12

Ok so they arent related, i think it might be A

Answer 13

Any set of pairs is a relation, so it's a relation. The question is, is this a function or not? It's only a function if each X value has a unique Y value.

Answer 14

So it all depends on the Y

Answer 15

It does not have a Y unique value

Answer 16

It depends on both of them together. (1, 2) (2, 2) is a function because each X has a unique Y value. But (1, 2) (1, 3), is not a function because the value x=1 has two conflicting y values: 2, and 3.

Answer 17

"Given this relation, if I tell you X is some number, can you tell me defiinitely what Y is?" if the answer is yes, then it's a function.

Answer 18

(1, 2) (3, 2) --> What's the value if x=1? It's 2. What's the value if X=4? It's 2. Since you can always answer the question, it's a function.

(1, 8) (1, 9) --> What's the value if x=1? You don't know. it could be either 8 or 9. Therefore it's not a function.

Answer 19

ok but idk, i think its neither ... because it has conflicting values...
