00:01 Hello everyone, let's solve the given question.
00:02 So, according to the question in the part 1st, 1, 2, 1 and on 2, it is because the each element have different images and range is equal to co -domain.
00:31 Now, moving to part 2nd, then it is neither 1, 1 nor on 2, it is because a and c have same image, b and range is not equal to co -domain...
