Can you tell me whether this is a function?

OpenStudy (anonymous):

Determine whether each relation is a function. Find the domain and range. 3. {(10,2) , (-10,2) , (6,4) , (5,3) , (-6,7)} The Domain is the set of x-coordinates, which is {10, -10, 6, 5, -6} The Range is the set of y-coordinates, which is {2, 4, 3, 7}

OpenStudy (anonymous):

put it up!

OpenStudy (anonymous):

seems like a function to me

Nnesha (nnesha):

if x values are repeat then its not function

Nnesha (nnesha):

so is there any value which is more than one @DrPepperx3

OpenStudy (anonymous):

Nesha is right. I just found that in my notes (beat me to it >:D)

OpenStudy (anonymous):

set of y-coordinates because it repeats {(2, 2, 4, 3, 7)}

Nnesha (nnesha):

don't care about y just look x values function or not function its just depend on x values

OpenStudy (anonymous):

ohhhh! ok and no nothing repeats in the x values

Nnesha (nnesha):

so its mean yes that is a function

OpenStudy (anonymous):

thank you!

Nnesha (nnesha):

my pleasure !!! :)
