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.

  • anonymous
Thank u and are u sure because this is really important
anonymous
  • anonymous
@mathmath333 is D the answer

@nikvist @mathmath333 @lehmad can u pls help
anonymous

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.
anonymous
  • anonymous
so That would be one of the answers would D be the other option @mathmath333 @lehmad
anonymous
  • anonymous
Would D be the other answer @lehmad

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.

  • anonymous
And we have B which we know is a function
anonymous
  • anonymous
So I have B and C has functions.
anonymous
  • anonymous
thank u can i ask u another question? this is the last one :)
anonymous
  • anonymous
Sure

Which relations are functions and which are not functions? Column A Column B 1. {(3, 2), (6, 4), (9, 6), (12, 8)} 2. {(2, 3), (2, 5), (3, 6), (9, 4)} 3. {(4, 2), (6, 3), (4, 8), (6, 6)} 4. {(3, 4), (5, 2), (6, 8), (6, 4)} A. function B. not a function

These confuse me can u pls help @lehmad
