x belongs to real number means x have all those values whose square is not negative
sox=1,2,3,4,1/22/3.. infinity
but x can not be √-1,√-2,•-3 ...
so domain is the group of numbers from which x belongs
domain ={0,1,2,3,1/2,1/3,2/3,-1,-2,-3,-1/2,-2/3..}
range is that group from which values of f(x) belongs
now x ki power 8 h
isliye x chahe positive ho ya negative
f(x) positive hi rahega
so Range ={0/1,2,3,4,5,1/2,1/4... positive infinity}
sox=1,2,3,4,1/22/3.. infinity
but x can not be √-1,√-2,•-3 ...
