Question
The set R = {(a, l), (2, b), (c,3)} is a relation from A = {a, b, c, d} to B = {1, 2, 3}.
Group starts
True or False
True, unselected
False, unselected
Solution
To determine if the set R = {(a, l), (2, b), (c,3)} is a relation from A = {a, b, c, d} to B = {1, 2, 3}, we need to check if each element in R is a valid pair where the first element is from A and the second element is from B.
Step 1: Check if (a, l) is a valid pair. Since a is in A and l is not in B, (a, l) is not a valid pair.
Step 2: Check if (2, b) is a valid pair. Since 2 is in A and b is not in B, (2, b) is not a valid pair.
Step 3: Check if (c, 3) is a valid pair. Since c is in A and 3 is in B, (c, 3) is a valid pair.
Since not all elements in R are valid pairs, we can conclude that the set R is not a relation from A to B.
