1.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.需要理由和举例. 答案 第一个是对的!存在反函数的条件是原函数必须是一一对应的,也就是说原函数有反函数,则反函
选转If a function is选转not a one-to-one function, what can be done to make it a one-to-o
thenf−1(_)=? Inverse Function: If we are given a function and we wish to know the inverse function, we need to know first if the given function is one-to-one. If the given function is one-to-one, the x and y values of the function will just interchang...
Assume that f is a one-to-one function. if f(6)=19, what is f−1(19)? Inverse Function: A function f−1(x) is said to be inverse of a one-one function f(x) if the condition f(f−1(x))=f−1(f(x))=x is satisfied for every x in the domain...

Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error. Tips You can nest any number of if statements. Each if statement requires an end keyword. Avoid adding a space after else within the elseif keyword (else if)...
This MATLAB function evaluates an expression, and executes a group of statements when the expression is true.
b) If {eq}f^{-1}(4) = 8 {/eq}, what is f(8)? Inverse Functions A function has an inverse only if it's one-to-one. This means that every possible value this function can take can only be computed by evaluating the function at one si...
