Question

Given R = {(x, y) : x, y ∈ W, x² + y² = 25}. Find the domain and Range of R.

Answer 1

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}
