thanks may you guys help me with some more

anonymous · Answer

sorry i meant yes... it passes the vertical line test.

anonymous · Answer

no its not. You cannot have two y values for one x value.

In the future, let's not give just direct answers please. 
An explanation and the user being involved in the answering process is much more along the guidelines of OpenStudy.

myininaya · Answer

if an x is assigned more than one y value then it is not a function

anonymous · Answer

so, it is not

myininaya · Answer

exactly because f(1)=-2 and -3

anonymous · Answer

right, its not a function

May you help me with another?

May you help me with a few more? Please

The range of the following relation: R {(3, -2), (1, 2), (-1, -4), (-1, 2)} is

 {-1, 1, 3}
 {-1, -1, 1, 3}
 {-4, -2, 2, 2}
 {-4, -2, 2}

anonymous · Answer

is that all it says? range could mean many different things

anonymous · Answer

they are asking for the range, meaning functions range and domain that kind of stuff

anonymous · Answer

I would say that if it does not continue any more that the range would be $$[-4,-2,2]$$

anonymous · Answer

the range is the y values

anonymous · Answer

coordinates are set up as an (x,y) so just use the y values of each coordinate to get the range

anonymous · Answer

ok thank you would you mind helping me some more

anonymous · Answer

sure thing

anonymous · Answer

The domain of the following relation: R {(6, -2), (1, 2), (-3, -4), (-3, 2)} is

 {-3, -3, 1, 6}
 {-4, -2, 2, 2}
 {-4, -2, 2}
 {-3, 1, 6}

anonymous · Answer

okay, Im gonna let you do this one. So the domain is all the x values, right? and if the coordinate is set up as (x,y) you would just have to look for the answer with the same x-valise. Do you think you can do that?

anonymous · Answer

yes the answer is a right?

anonymous · Answer

yeah. and the answer to the one before this was c if i didn't tell you

anonymous · Answer

not d
