内容提示: ONE-TO-ONE AND ONTO FUNCTIONS The concept of one-to-one functions is necessary to understand the concept of inverse functions. One-to-One Functions If a function has no two ordered pairs with different first coordinates and the same second coordinate, then the function is called ...

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...

Show that the functionf:R→R, defined asf(x)=x2, is neither one-one nor onto. One-to-One and Onto Functions: Recall the definitions for the following types of functions. Letf:A→Bbe a function. f x1,x2∈A x1=x2 f(x1)=f(x2) ...
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...

What are one-to-one and onto functions? Explain with example. Functions Functions are perhaps one of the most ubiquitous mathematical quantities. They are used in every branch of mathematics that is beyond basic arithmetic. A function is a quantity that defines how two sets of quantities a...
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。
