一、一一对应函数(one-to-one function) 若函数 f 从未取同一个值至少两次,即对任意 x1≠x2 有f(x1)≠f(x2) ,则称其为一一对应函数. 二、水平线检验 当且仅当没有任何一条水平线与函数图象曲线相交超过一次时,该函数是一一对应的. 如下例: 图记1.6-1 图左曲线相应的函数一一对应,图右的不一一对应...
∴inverse function Let f be a one-to-one function. Its inverse,denoted by f1, is the function that satisfies the equations f1( f(x))=x for all values o f x in the do main o f f,and f( f-'(x))=χ for all values o f xin the domain o f f'.For example,the function y=...

第二个是错的!可微分的函数太多了!x的三次方,微分后是d(x^3)=3x^2 dx其中3x^2是3x^2就是f'(x),显而易见,他不是one to one 的!相关推荐 11.If a function has an inverse function,then the inverse function is one-to-one.2.If a function is diffrentiable,the f'(x) is one-to-one....
Which is the correct inverse of the one-to-one function: {eq}\displaystyle f(x)=\frac{3x-1}{x+2} \\ \displaystyle (a)f^{-1}(x)=-\frac{2x-1}{x-3}, x \neq 3 \\ \displaystyle (b)f^{-1}(x)=\...
Section 3: One-to-one, Onto, and Inverse Functions• In this section, we will look at three special classes of functions and see how their properties lead us to the theory of counting. • So far, we have the general notion of a function :X → Y, but in terms of the comparative...
One-to-one FunctionThe function is a mapping from inputs to outputs such that each input has a single output. If the function is such that each input has a single and unique output, then it is called a one-to-one function.Answer and Explanation: ...
