A relation R is given by the set {(x,y)/y=x+3,xe {0,1 2,3,4,5,}}Detemine its domain and range |

Answer» x = {0, 1, 2, 3, 4, 5} y = x + 3 When x = 0 ⇒ y = 0 + 3 = 3 When x = 1 ⇒ y = 1 + 3 = 4 When x = 2 ⇒ y = 2 + 3 = 5 When x = 3 ⇒ y = 3 + 3 = 6 When x = 4 ⇒ y = 4 + 3 = 7 When x = 5 y = 5 + 3 = 8 R = {(0, 3) (1, 4) (2, 5) (3, 6) (4, 7) (5, 8)} Domain = {0, 1, 2, 3, 4, 5} Range = {3, 4, 5, 6, 7, 8} |
