Which of the following relations are functions?R1 ={(3, 4),(4, 5),(6, 7),(8, 9)}, R2 ={(3, 4),(4, 5),(6, 7),(3, 9)}, R3 ={(-3, 4),(4, -5),(0, 0),(8, 9)}, R4 ={(8, 11),(34, 5),(6, 17),(8, 19)}

Which of the following relations is not a function?*R = {(1,2), (1,4), (3,1), (5,1)}R = {(1,2), (3,4), (2,1), (5,2)}R = {(2,1), (4,4), (3,1), (5,1)}R = {(1,2), (3,4), (2,1), (5,1)}

Select the correct answer.Which relation does not represent a function? A. {(3, 0), (0, 3)} B. {(6, -2), (5, -2)} C. {(3, 4), (3, 5)} D. {(5, 5), (-5, -5)} E. {(1, -2), (-2, 1)}

Which of the following sets of ordered pairs represents a function?{(-1,4),(1,4),(2,4),(-2,4)}{(-2,1),(-1,3),(2,1),(-2,2)}{(2,2),(3,3),(4,4),(2,1)}{(-1,3),(-1,4),(-1,5),(-1,6)}

Given the sets of ordered pairs, determine if they represent a relation or a function. If it is a function,specify the domain and range. (Criteria A)a) {(1,2),(2,3),(1,5),(4,6)}{(1,2),(2,3),(1,5),(4,6)}b) {(3,4),(2,7),(5,2),(3,1)}{(3,4),(2,7),(5,2),(3,1)}c) {(2,3),(5,6),(2,7),(8,1)}{(2,3),(5,6),(2,7),(8,1)}d) {(1,3),(2,5),(3,7),(4,9)}{(1,3),(2,5),(3,7),(4,9)}

Which set of ordered pairs is a function fromA = {a, b, c, d} to B = {1, 2, 3, 4, 5, 6}? R4 = {(a, 2), (b, 2), (c, 6), (d, 2), (c, 5)} R3 = {(a, 3), (b, 2), (a, 4),(c, 5), (d, 4)} R1 = {(a, 3), (b, 3), (c, 4), (d, 1)} R2 = {(a, 1), (a, 4), (b, 1), (c, 5), (d, 4)}
