lynfran · Answer

yep the domain is the x value and its suppose to be a -4 not a +4 there
the range is the y value

lynfran · Answer

for (-4,2) domain; x=-4  range; y=2...

anonymous · Answer

Okay

anonymous · Answer

How is the domain 4. Is it because the domain has 4 numbers.

lynfran · Answer

well actually all the range value is the same and if you want u could have put it by stating 
for example (10,-15) domain; x=10.....range; y=-15 or u could put it in a table |dw:1435683150487:dw|

anonymous · Answer

Kay. Not sure why i'll need 10 and -15 though

lynfran · Answer

no you dont need to include that....i was just given you an example by using (10,-15)

lynfran · Answer

so your answer shd be 
x=-9 ,  y=2
x=-4 ,  y=2
x=3 , y=2  etc

anonymous · Answer

Okay. so i messed up?

lynfran · Answer

no just need to state what was x= to... (domain).
and state what was y=to....(range)
