onto function
The function is bijective (one-to-one and onto or one-to-one correspondence) if each element of the codomain is mapped to by exactly one element of the domain. (That is, the function is both injective and surjective.) A bijective function is a bijection. ,A function ƒ : A→B is called an onto function if the range of ƒ is B. ,One to One Onto Function. A function f which is one to one as well as onto function, such type of function said to be one one onto or bijective function. So for bijective function, a function must be both one one and onto. Examples of Onto Functions Examp,An onto or a surjective function is a function in which each and every element of the range is related to at least one element in the domain, i.e. every output must be originated from at least one input. In onto function, there cannot be any range element,A是定義域B是值域 那onto的意思簡單來說就是 對於每一個B裡面的元素y 都會存在x 使得f(x) = y (x是A裡面的元素) 這裡並沒有限定x要是唯一的至少要有一個這樣的x就是了 再說的白話一點 就是值域裡面的每一個元素都要被對應到 給你例子 定義域:-1 ,1 ,2 ,3 } 值域:1 ,2 ,3} f(x) = |x| 值域裡面有1 2 3 ---> 1 = f(-1) 1 = f(1) 2 = f(2) ,Introduction to surjective and injective functions. ,In mathematics, a function f from a set X to a set Y is surjective (or onto), or a surjection, if for every element y in the codomain Y of f there is at least one element x in the domain X of f such that f(x) = y. It is not required that x is unique; the , I'm going to try to approach this intuitively, but I will first do other definitions. Firstly, an “onto” function is “surjective”, and I'll get into the definition of this. Functions can be injective and surjective, both, or neither. So, injectiv,,一對一函數( one - to - one function )： 設f：A(定義域)→B(對應域)，若f滿足：任意的a、b∈A，a≠b⇒f(a) ≠f(b) 則稱f為一對一函數。也就是f為一對一⇔ ( a≠b⇒f(a) ≠f(b) ) ⇔ (f(a) ＝f(b) ⇒a＝b ) 映成函數( onto function )： 設f：A→B，若f滿足：所有的y∈B，存在x∈A，使得f(x)＝y 則稱f為映成函數。也就是f為映成⇔ f(A) (值域) ＝ B( ...
