A one-to-one or injective function.
Is called "function".
A function is a special type of relation. So first let's see what a relation is. A relation is a diagram, equation, or list that defines a specific relationship between groups of elements. Now a function is a relation whose every input corresponds with a single output.
This is true. Furthermore, functions can be broken down into one-to-one (each input provides a different output), and onto (all of Y is used when f(x) = y).

A Function
It's a type of function
No, not every relation is a function. In order for a relation to be a function, each input value must map to exactly one output value. If any input value maps to multiple output values, the relation is not a function.
It is a bijective function.
That's a proper function, a conformal mapping, etc.
Is called "function".

A relation is a mapping or pairing of input values with output values.
A relation is a function if every input has a distinct output.
