1/x是x的倒数。 Function G is the inverse of function F. 函数G是函数F的反函数。 Inverse Reverse是“相反的”的意思。通常用于表达朝着相反的方向变化的语境。比如汽车的倒挡、汽车行驶过程中的调头就是Reverse。 Example: Reverse your car at the next cross. 下个十字路口调头行驶。 Reverse发布...
x=f(y), solving the equation forx. If this can be done in a unique way, then the function is invertible and the solution found will give the expression for the inverse function. When we are finished, we replacexwithf−1(x)to indicate that it is the inverse of the functionf(x)....
An inverse function goes the other way!Let us start with an example:Here we have the function f(x) = 2x+3, written as a flow diagram:The Inverse Function goes the other way:So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the...
解析 Replace ( f(x)) with ( y). ( y=(log)(x)) Interchange the variables. ( x=(log)(y)) Solve for ( y). ( y=(10)^x) Solve for ( y) and replace with ( f^(-1)(x)). ( f^(-1)(x)=(10)^x) 反馈 收藏 ...

What is the inverse of the function g(x) = -(2/3)x - 5? Calculate g'(x), where g(x) is the inverse of f(x). f(x) = {x \over {x - 1 Let g(x) be the inverse of the function f(x), and f'(x) = \frac{1}{1 + x^3}. Then g(x) is equal to . ...
There is an inverse if the function is one-to-one or restrictions imposed to give this state of affairs. However, the function y = sin x gives many values of x for the same value of y. To obtain an inverse we have to restrict the domain of the function to −π/2 to +π/2. ...
"Let f and g be two functions such that f(g(x))=x and g(f(x))=x.The function g is called an inverse function of the function, f and vice versa".Since f(g(x))=x and g(f(x))=x, the functions f(x)= 1(x+1) and g(x)= (1-x)x are inverse functions of each other...
The arcsine of x is defined as the inverse sine function of x when -1≤x≤1.When the sine of y is equal to x:sin y = xThen the arcsine of x is equal to the inverse sine function of x, which is equal to y:arcsin x = sin-1 x = y...
