Q10 of 76 Page 2

If R = {(x, y) : x, yW, 2x + y = 8}, then write the domain and range of R.

Here, R={ (x, y) :x ,yϵ W,2x+y=8}


={(0,8) ,(1,6) ,(2,4) ,(3,2) ,(4,0)}


Now we know, Domain is the set which consist all first elements of ordered pairs in relation R.


So, Domain(R)= {0,1,2,3,4}


Also we know, Range is the set which consist all second elements of ordered pairs in relation R.


So, Range(R)={0,2,4,6,8}
