Find the domain and range of the following(i) f = {(1, 2), (2, 3), (3,

1.	Find the domain and range of the following(i) f = {(1, 2), (2, 3), (3, 4), (4, 5) (5, 6)}(ii) R = {(-2, 4), (-1,1), (2,4), (1,1) (-3, 9)}
Answer» (i) f = {( 1,2), (2, 3), (3, 4), (4, 5) (5, 6)} Domain = {1,2, 3,4, 5} Range = {2, 3, 4, 5, 6} (ii) R = {(-2,4), (-1, 1),(2,4), (1,1) (-3,9)} Domain = {-2, -1,2, 1,-3} (or) = {-3,-2,-1, 1,2} Range = {4, 1, 9} (or) {1, 4, 9}

Find the domain and range of the following(i) f = {(1, 2), (2, 3), (3, 4), (4, 5) (5, 6)}(ii) R = {(-2, 4), (-1,1), (2,4), (1,1) (-3, 9)}

Answer»

(i) f = {( 1,2), (2, 3), (3, 4), (4, 5) (5, 6)}

Domain = {1,2, 3,4, 5}

Range = {2, 3, 4, 5, 6}

(ii) R = {(-2,4), (-1, 1),(2,4), (1,1) (-3,9)}

Domain = {-2, -1,2, 1,-3} (or)

= {-3,-2,-1, 1,2}

Range = {4, 1, 9} (or) {1, 4, 9}
