Can you tell me whether this is a function?

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}

put it up!

@Nnesha

@paki

@grray7

seems like a function to me

if x values are repeat then its not function

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

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

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

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

ohhhh! ok and no nothing repeats in the x values

so its mean yes that is a function

thank you!

my pleasure !!! :)
