Functions can map elements from the domain to the codomain in many ways. A function may "hit" every element in the codomain, or it may "miss" some. It may assign more than one x to a y or it may assign exactly one x to each y. We will understand our function better if we know...

In a one-to-one function, given any y there is only one x that can be paired with the given y. A graph of a function can also be used to determine whether a function is one-to-one using the horizontal line test: If each horizontal line crosses the graph of a function at no...
onto和one to one的区别：意思不同。onto 英 [ˈɒntə] 美 [ˈɑːntə]prep.(与动词连用，表示朝某处或某位置运动）向，朝；朝向，面向（某个方向）。one to one 英 [ˌwʌn tə ˈwʌn] 美 [ˌwʌn t...
onto 是漫射 台版翻译叫映成函数 映成函数(onto function)：设f：A→B，如果f(A)=B，则f是映成函数。换言之，B理的每一分子都出现作A的像，那f是映成函数。
根据离散数学及其应用第七版原版中的解释，one- to-one是指单射，onto指满射，一一对应或双射则是用bijective。参考资料：<<Discrete Mathematics and Its Applications>> 7th Edition

one-to-one,意思是"一对一"通常指一对一映射,或"一一对应映射."ONTO意思"到上" ,通常指满映射或满射,INTO意思"到内" ,通常指单射或一对一映射,设f是A到B的函数,如果对任意属于B的y,均存在属于A的x,使得f(x)=y,则称f... 分析总结。 onto意思到上通常指满映射或满射into意思到内通常指单射或一对...
