Question:

1) Find the domain and range of relation R={(-1,1),(1,1),(-2,4),(2,4)}

Answer:

Given, relation R = {(-1, 1), (1, 1), (-2, 4), (2, 4)}

Now, domain (R) = {-1, 1, -2, 2} = {-2, -1, 1, 2} {(x, y): x is the domain of the relation}

and range (R) = {1, 4} {(x, y): y is the range of the relation}
