bijective function in discrete mathematics

What are the types of functions in discrete mathematics?
In this section, we will learn about other types of function.
One to One Function.
A function f: A → B is One to One if for each element of A there is a distinct element of B. Many to One Function. Onto Function. One – One and Onto Function. Identity Function. Constant Function. Polynomial Function. Modulus Function.
What is a bijective function in logic?
A function f:A→B is bijective (or f is a bijection) if each b∈B has exactly one preimage.
Since "at least one'' + "at most one'' = "exactly one'', f is a bijection if and only if it is both an injection and a surjection.
A bijection is also called a one-to-one correspondence.
Functions are surjections when at least one x in the x data set points to every y in the y data set.
So, you can have more than one x pointing to the same y.
Surjections are also called onto.
Functions are bijections when they are both injective and surjective.

What is an example of a bijection function?

Some examples of Bijective functions are: Linear Functions: f(x) = x, g(x) = x + 10, h(x) = 5x – 5, etc.
Polynomial Functions: f(x) = x³, g(x) = x³ – 1.
Exponential Functions: f(x) = e^x, where f : R → (0, ∞)

What is Bijective Function? A function is said to be bijective or bijection, if a function f: A → B satisfies both the injective (one-to-one function) and surjective function (onto function) properties. It means that every element “b” in the codomain B, there is exactly one element “a” in the domain A.
