Introduction

When dealing with functions, particularly rational functions, understanding the domain is crucial. The domain of a function is the set of all possible input values (x) for which the function is defined. In the case of a rational function, the domain is restricted by the values of x that make the denominator equal to zero. In this article, we will explore the domain of the function {\left(\frac{g}{f}\right)(x)$}$ given that {f(x) = x$}$ and {g(x) = 1$}$.

Understanding the Function

To begin with, let's analyze the given functions. We have {f(x) = x$}$ and {g(x) = 1$}$. The function {\left(\frac{g}{f}\right)(x)$}$ is a rational function, where the numerator is {g(x)$}$ and the denominator is {f(x)$}$. Substituting the given functions, we get:

{\left(\frac{g}{f}\right)(x) = \frac{1}{x}$}$

Domain of a Rational Function

The domain of a rational function is the set of all real numbers except those that make the denominator equal to zero. In this case, the denominator is {x$}$, and it will be equal to zero when {x = 0$}$. Therefore, the domain of the function {\left(\frac{g}{f}\right)(x)$}$ is all real numbers except {x = 0$}$.

Conclusion

In conclusion, the domain of the function {\left(\frac{g}{f}\right)(x)$}$ given that {f(x) = x$}$ and {g(x) = 1$}$ is {x \neq 0$}$. This means that the function is defined for all real numbers except {x = 0$}$.

Final Answer

The final answer is {x \neq 0$}$.

Introduction

In our previous article, we explored the domain of a rational function given two specific functions, {f(x) = x$}$ and {g(x) = 1$}$. We found that the domain of the function {\left(\frac{g}{f}\right)(x)$}$ is all real numbers except {x = 0$}$. In this article, we will answer some frequently asked questions related to the domain of a rational function.

Q&A

Q1: What is the domain of a rational function?

A1: The domain of a rational function is the set of all real numbers except those that make the denominator equal to zero.

Q2: How do I find the domain of a rational function?

A2: To find the domain of a rational function, you need to find the values of x that make the denominator equal to zero. These values are excluded from the domain.

Q3: What happens if the denominator is equal to zero?

A3: If the denominator is equal to zero, the function is undefined at that point. This means that the function is not defined for that value of x.

Q4: Can a rational function have a domain of all real numbers?

A4: Yes, a rational function can have a domain of all real numbers if the denominator is never equal to zero.

Q5: How do I determine if a rational function has a domain of all real numbers?

A5: To determine if a rational function has a domain of all real numbers, you need to check if the denominator is never equal to zero. If the denominator is never equal to zero, then the function has a domain of all real numbers.

Q6: What is the difference between the domain and the range of a function?

A6: The domain of a function is the set of all possible input values (x) for which the function is defined. The range of a function is the set of all possible output values (y) for which the function is defined.

Q7: Can a function have a domain of all real numbers and a range of all real numbers?

A7: Yes, a function can have a domain of all real numbers and a range of all real numbers if the function is a one-to-one correspondence.

Q8: How do I determine if a function is a one-to-one correspondence?

A8: To determine if a function is a one-to-one correspondence, you need to check if the function is both injective and surjective.

Q9: What is the difference between an injective and a surjective function?

A9: An injective function is a function that maps each input value to a unique output value. A surjective function is a function that maps each output value to at least one input value.

Q10: Can a function be both injective and surjective?

A10: Yes, a function can be both injective and surjective if it is a one-to-one correspondence.

Conclusion

In conclusion, the domain of a rational function is the set of all real numbers except those that make the denominator equal to zero. We have answered some frequently asked questions related to the domain of a rational function, including how to find the domain, what happens if the denominator is equal to zero, and how to determine if a function is a one-to-one correspondence.

Final Answer

The final answer is that the domain of a rational function is the set of all real numbers except those that make the denominator equal to zero.
