Which relation below is a function from (A={0,1,2}) to (B={0,1,2,3}) but has the same image for two elements of (A)?

Answer and explanation

Correct answer: ({(0,1),(1,1),(2,3)})

In option (B), both (0) and (1) have image (1), and every input has exactly one image. A common image does not prevent a function.
