Answer:
Hey buddy whatsup? All good
Coming to the question fig 1 and 3 aren't functions
Coz.... Reason for fig 1... Every distinct element of domain must have a unique element in codomain, but in this fig the same element has more than two unique elements which is a relation not a function.
Reason for fig 3 every element in domain must have an unique element in codomain but in this fig the element c doesn't have any unique element hence it isn't a function.....
Thank you
