If `R={(x,y): x,y in W, x ^(2)+y^(2)=25}`, then find the domain and range of R.

Text Solution

Verified by Experts

We have,
`R={(x,y):x,y in W,x^(2) +y^(2)=25}`
`={(0,5),(3,4),(4,3),(5,0)}`
Domain of `R -= `Set of first element of ordered of ordered pairs in R
` -={0,3,4,5}`
Range of `R-=` Set of second element of ordered pairs in R
` -= {5,4,3,0}`
