The inverse of any function should be immediately clear. The inverse of x + 2 is x − 2. (Example 1) The inverse of x2 is x½. (Problem 2.) In Topic 21 we will see that the inverse of a logarithmic function, y = logbx, is the exponential function y = bx. And in Topic...
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...

The inverse of a function y = f[x] is the function x = g[y] whose “rule undoes what the rule for f does.” For example, if y = f[x] = x2, then x=g[y]=y, at least when x≥ 0. These two functions have the same graph if we plot g with its independent variable where...
Inverse Function Defined The mathematical definition of a function is a relation (x, y) for which only one value of y exists for any value of x. For example, when the value of x is 3, the relation is a function if y has only one value,...
For example, consider the function f(x)=x3+4f(x)=x3+4. Since any output y=x3+4y=x3+4, we can solve this equation for xx to find that the input is x=3√y−4x=y−43. This equation defines xx as a function of yy. Denoting this function as f−1f−1, and writing x=f...
Can someone tell me how is it possible to find the inverse of this function in whichzis a complex number and cannot be zero. ,aandbare constant. How to solve this function for ? Data (Example) The following is obtained using the following input: ...
What is the inverse of the functionf(x)=4x+8? Inverse Functions: Two functions are said to be inverse of one another if they reverse each other. Therefore, an inverse function is a function that will undo anything done by the original function. For example, if a function goes fromatob,...
Another property is that the graph of a function and its inverse function are reflections of each other across the line y = x. This reflection property visually demonstrates how the inverse function reverses the action of the original function. Let's explore another example to further illustrate ...
