Which of the following relations are functions from A to B write their domain and range if it is not a function give reason ?`f={(a,b),(b,c),(c,b),(d,c)},A={a,b,c,d,e},B={b,c}`

Explanation

To determine whether the relation \( f = \{(a,b), (b,c), (c,b), (d,c)\} \) is a function from set \( A \) to set \( B \), we will follow these steps:

### Step 1: Identify the sets A and B
Given:
- \( A = \{a, b, c, d, e\} \)
- \( B = \{b, c\} \)

### Step 2: List the elements of the relation f
