Here is an example: Example of a one-to-one function The graph above depicts the function {eq}f(x)=x+2 {/eq}. This graph does not map x-values to the same y-value anywhere so it is a one-to-one function. Here are more examples of one-to-one functions:...
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...

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 of x in the do main of f,and f( f-'(x))=χ for all values of xin the domain of f'.For example,the function y=f(x)=x`...
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....
