Question

R = {(x,y):y=x+1} and A = {1, 2, 3, 4, 5,6} Write R in roster form​

Answer 1

Step-by-step explanation:

Given: A = {1, 2, 3, 4, 5, 6} (i) R = {(x, y): y = x + 1} So, R is Roster Form is, R = {(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)} (ii) Dom(R) = {1, 2, 3, 4, 5} Range(R) = {2, 3, 4, 5, 6} (iii) Here, y = x + 1 So, the CoD(R) = {1, 2, 3, 4, 5, ...}
