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....
Let f denote a one-to-one function y = f (x). The inverse of f, denoted by f -1 , is a function such that 1. f -1 (f (x)) = x for every x in the domain of f and 2. f (f -1 (x)) = x for every x in the domain of f -1 . I have example in Calc...

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...
Assume that {eq}f {/eq} is a one-to-one function. If {eq}f^{-1}(3) = 2 {/eq}, what is {eq}f(2) {/eq}? One-One and Inverse Function: The function is one-one when the function satisfies the mathematical condition {eq}f(x_1)=f(x_2)\Rightarrow x_1=x_...
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 one-to-one. This sounds confusing, so let’s consider the following: In a one-to-one function, given any y there is only one x that...

The 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:
