Students were asked to answer a question at school and to assert what is most important for them to succeed. One which response stood out from the rest was practice. Successful people absolutely not born successful; they become successful thru hard work and perseverance. This is how you can get your goals. in this article, some question and answer examples that you could definitely utilize to enhance your knowledge and gain insight that will help you to keep up your school studies.

## Question:

Which of the following is written as a rational function?

A.G(x)=-2x

B.P(x)=3x+4

C.Q(x)=x^2-8x+1

D.F(x)=x+2/5x

## Answer:

We have to identify the rational function among the given functions.

**Rational function is a function that is the ratio of two polynomials. It is rational because one polynomial is divided by the other polynomial, like a ratio.**

1. Consider the first function , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

2. Consider the second function , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

3. Consider the third function , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

4. Consider the fourth function , since it is a function that is the ratio of two polynomials (x+2) and (5x). So, it is a rational function.

**So, Option D is the correct answer.**

From the answer and question examples above, hopefully, they could help the student sort out the question they had been looking for and notice of everything stated in the answer above. You would probably then have a discussion with your classmate and continue the school learning by studying the subject jointly.
