But an Injective Function is stricter, and looks like this:"Injective" (one-to-one)In fact we can do a "Horizontal Line Test":To be Injective, a Horizontal Line should never intersect the curve at 2 or more points.(Note: Strictly Increasing (and Strictly Decreasing) functions are ...
There is an important quality about injective functions that becomes apparent in this example, and that is important for us in defining an injective function rigorously. Suppose you told me that the function that assigns boys to girls is injective, and suppose you also told me that “boy 1” ...

(a) A nonempty set S is countable if and only if there exists surjective function f:N->S (b) A nonempty set S is countable if and only if there exists a injective function g:S->NThere are two way proves for both (a) and (b)...
If a function is an injective function, each element's image in the domain is different in the codomain. Surjective function is a function that each element in the codomain is an image of at least one element in the d...
One of these approaches uses accessibility functions between flows of time to study the basic properties of the functions, such as being total or partial, injective, surjective, etc. The completeness of certain systems expressing many of these properties, with the exception of surjectivity, has ...
Re: injective/surjective/bijective help!!!Do functions have to be continuous? If no, then... a) Every decreasing function from R to R is surjective False. f(x) = -x for all x <= 0, f(x) = -x - 1 for all x > 0.
In the paper we construct several algebraic structures (vector spaces, algebras and free algebras) inside sets of different types of surjective functions. Among many results we prove that: the set of everywhere but not strongly everywhere surjective complex functions is strongly c-algebrable and that...
