Question

16. The domain of Ris
. If
R= {(x,y): x, yeW. x2 + y2 = 25}​

Answer 1

Answer:

We have, R = {(x,y):x,y∈ W, x2 + y2 = 25}

= {(0,5), (3,4), (4, 3), (5,0)}

Domain of R = Set of first element 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}
