A one to one function is a special function that maps every element of the range to exactly one element of its domain. This means that the outputs never repeat. For example, the function g (x) = x - 4 is a one to one function since it produces a different answer for every input. In a one-to-one function, every element in the range of the function corresponds to exactly one element in its domain.

What is one to one function?
One to one function or one to one mapping states that each element of one set, say Set (A) is mapped with a unique element of another set, say, Set...
What is an injective function?
An injective function is nothing but one to one function, where each element of one set is mapped with each element of another set.
Give examples of one to one function.
If f:R→ R is a function, then the examples of one to one are: f(x) = 2x f(x) = x 3 f(x) = 3x+1 f(x) = x/3
Which function is not said to be one to one?
If a horizontal line can intersect the graph of the function, more than one time, then the function is not mapped as one-to-one.
What is onto function?

What is one to one function?
One to One Function is a mathematical function where each element in the domain maps to a unique element in the codomain. This article explores the concept of One to One Function or One-One Function in detail including its definition and examples which help you understand the concept with ease.

Is a one to one function an injective function?
A one to one function is also considered as an injection, i.e., a function is injective only if it is one-to-one. The contrapositive of this definition is a function g: D -> F is one-to-one if x 1 ≠ x 2 ⇒ g (x 1) ≠ g (x 2). Let us visualize this by mapping two pairs of values to compare functions that are and that are not one to one.

What is the difference between one to one and many to one functions?
The difference between one-to-one and many-to-one functions is whether there exist distinct elements that share the same image. There are no repeated images in a one-to-one function. The identity function on any nonempty set A IA: A → A, IA(x) = x, maps any element back to itself.

What if a function 'f' from a set 'a' to 'B' is one-to-one?
A function 'f' from a set 'A' to set 'B' is one-to-one if no two elements in 'A' are mapped to same element in 'B.' Let's consider these two diagrams. For diagram A we realize that 10 maps to 1, 20 maps to 2 and 30 maps to 3. However for diagram B it is clear that 10 and 30 maps to 3 and then 20 maps to 1.

How do you find a one-one function?
In other words, one-one functions are exactly the monomorphisms in the category set of sets. If f: X → Y is one-one and P is a subset of X, then f-1(f (A)) = P. Thus, P can be retrieved from its image f (P). If f: X → Y is one-one and P and Q are both subsets of X, then f (P ∩ Q) = f (P) ∩ f (Q).
