If R is the relation defined on N so that
x2 + 2y = 100 then R =
a) {(48, 2), (42, 4), (32, 6)}
b) {(2, 48), (4, 42), (8, 18)}
c) {(2,48), (4,42), (6, 32), (8, 18)}
d) None of these.

Answer:
(c)
Step-by-step explanation:
x² + 2y = 100 ⇔ y = - x² + 50
(c) R = {(2,48), (4,42), (6, 32), (8, 18)}
48 = - (2)² + 50
42 = - (4)² + 50
32 = - (6)² + 50
18 = - (8)² + 50
