QUESTION 1 Let OR be defined by the formula R = {(x,y) ERXR : y -2= x2 }. Then 2 E Rng(OR). O True O False QUESTION 2 Let the relation be J = {(x,y) ERXR : y = V4-2x }, then Dom() = (-0o, 4]. O True O False QUESTION 3 Relations R and S are defined by R = {(1,5), (2,2), (3,4), (5,2) } and S = {(2,4), (3,4), (3,1), (5,5)} . Then So R = {(1,5), (5,4),(2,4) }. O True O False QUESTION 4 Relations R and S are defined by R = { (1,5), (2,2), (3,4), (5,2)} and S = {(2,4), (3,4), (3,1), (5,5)}. Then Dom (R o S) = O { 1, 2, 3, 5} O ( 2 , 3 , 5 } O { 2 , 5 } O ( 3, 5 }
