A function is a relation whose mapping is a bijection.

It is simply a mapping. It could be a function but there are several conditions that need to be met before the mapping can become a function and there is no basis for assuming that those conditions are met.

A mapping is a function.f: A -> BThis statement says f is a function and it maps from set A to set B.In order for f to be a function, for every element of A, there must exist uniquely f(a) in B.

direct mapping doesn't need replacement algorithm

If, at any time, a vertical line intersects the graph of a relationship (or mapping) more than once, the relationship is not a function. (It is a one-to-many mapping and so cannot be a function.)

A one-to-one function, a.k.a. an injective function.

It is a square root mapping. This is not a function since it is a one-to-many mapping.
