In mathematics, an inverse function is a function that undoes the effects of another function. In other words, if f is an inverse function of g then g(f(x)) = x and f(g(x)) = x. This means that inverse functions can be used to solve a wide variety of problems. In this article, we will provide 1-4 inverse functions answers to help you understand how these functions work.

## 1. The Inverse of the Identity Function

The inverse of the identity function is the identity function itself. The identity function is a special function that returns the same value as its argument. This means that the inverse of the identity function is y = x. In other words, if x is the argument of the identity function, then y = x will be the result.

## 2. The Inverse of a Linear Function

The inverse of a linear function is a reciprocal function. A reciprocal function is a function whose output is the reciprocal of its input. For example, if the linear function is y = 2x, then the inverse of this function is y = 1/2x. This means that if x is the argument of the linear function, then y = 1/2x will be the result.

## 3. The Inverse of a Quadratic Function

The inverse of a quadratic function is a square root function. A square root function is a function whose output is the square root of its input. For example, if the quadratic function is y = x2, then the inverse of this function is y = √x. This means that if x is the argument of the quadratic function, then y = √x will be the result.

## 4. The Inverse of an Exponential Function

The inverse of an exponential function is a logarithmic function. A logarithmic function is a function whose output is the logarithm of its input. For example, if the exponential function is y = 2x, then the inverse of this function is y = log2x. This means that if x is the argument of the exponential function, then y = log2x will be the result.

Inverse functions are useful for solving a variety of problems. In this article, we have provided 1-4 inverse functions answers to help you understand how these functions work. We hope that this article has been helpful in understanding inverse functions and their applications.
