If A = {1, 2, 3}, B = {a, b, c} and R = {(1, a), (2, a), (3, b)} then R is____?
- One-one function
- Onto function
- Into function
- None of these
Explanation
Every element of set A is related to an element in B, so it's a function.
Since not every element of B is mapped (e.g., c is not an image), it’s into function.
