Answer 3

@mathmath333

Answer 4

pls help me

Answer 5

The answer would be D. This is because if you use the vertical line test (a vertical line going through the given lines) you see that D would only have 1 x value with 1 y value, making it a function.

Answer 6

Thank u and are u sure because this is really important

Answer 7

@mathmath333 is D the answer

Answer 17

this is for the next question :)

Answer 18

@nikvist @mathmath333 @lehmad can u pls help

Answer 19

Right off the bat we can tell that the second option you posted is a function because the vertical line test is giving us 1 x value every 1 y value.

Answer 20

so That would be one of the answers would D be the other option @mathmath333 @lehmad

Answer 21

Would D be the other answer @lehmad

Answer 22

pls help me

Answer 23

@lehmad pls help me

Answer 24

Taking a guess here (sorry, maybe it'll put some ideas that will help you solve)
D I don't think would be the answer because there are 2 of the same x values.
C I believe is a function because it does not interfere will having more than 1 x value.
Finally A I think would not be a function because it has, as we can see, two of the same x values.

Answer 25

And we have B which we know is a function

Answer 26

So I have B and C has functions.

Answer 27

thank u can i ask u another question? this is the last one :)

Answer 28
