Answer:

#x inRR,yinRR#

Explanation:

Since any value of #x# only gives one value of #y# ane each value of #y# has one corresponding #x# value, we don't have to place any limits.

Also, all values of #x# gives a value for #y#, and all values for #y# are possible, we say that domain is #x inRR# and the range is #yinRR#, where #inRR# which means it contains all values in the real set (#RR={0,-3,3.54,8.2223,1/3,e,pi,etc.}#)
