. Identify the domain and range of the relation. {(-9, 2), (-4, 2), (3, 2), (9, 2)}
domain is the set of x's range is the set of y's
So the domain is \(\{-9,-4,3,9\}\)
what is the range? Note that in a set we do not repeat elements..
@dwatts158 ?
yes 2,2,2,2
you need to put them in set brackets because range is a set of values not just the values listed and we don't double list elements in a set, so it would be \(\{2\}\) Make sense?
oh ok. (2,2,2,2)
wait {2,2,2,2}
no
this is the third time I will say it. WE DONT LIST ELEMENTS TWICE IN A SET. The range is \(\{2\}\) that's the answer
:)
ok thank you.
that looks a lot harsher than I mean it to be
lol
I understand. :)
technally you could have said that because they are the exact same thing \(\{2,2,2,2,2\}=\{2\}=\{2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2\}\)
but your teacher wont like it...
