## What are 2 examples of inverse functions?

An example is also given below which can help you to understand the concept better. Step 4: Replace y with f-1(x) and the inverse of the function is obtained….Types of Inverse Function.

Function Inverse of the Function Comment
1/x 1/y x and y not equal to 0
x2 √y x and y ≥ 0
xn y1/n n is not equal to 0
ex ln(y) y > 0

### What is inverse function in discrete mathematics?

An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing.

How do you find the inverse of a function in discrete mathematics?

Therefore, we can find the inverse function f−1 by following these steps:

1. Interchange the role of x and y in the equation y=f(x). That is, write x=f(y).
2. Solve for y. That is, express y in terms of x. The resulting expression is f−1(x).

What is a real world example of an inverse function?

The inverse of a function tells you how to get back to the original value. We do this a lot in everyday life, without really thinking about it. For example, think of a sports team. Each player has a name and a number.

## Can you give more examples of inverse?

Examples of inverse operations are: addition and subtraction; multiplication and division; and squares and square roots.

### What do you mean by inverse function?

: a function that is derived from a given function by interchanging the two variables y = ∛x is the inverse function of y = x3 — compare logarithmic function.

What is an example of an inverse relationship?

Inverse Relationship Examples: Speed and the time it takes to travel are inversely related. As you increase your speed, the travel time decreases. As you decrease your speed, the travel time increases. The Law of Supply and Demand is an inverse relationship.

Which function has an inverse that is a function?

Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y….Inverses in calculus.
