## What are not examples of rational functions?

Non-Examples of Rational Functions The function R(x) = (sqrt(x) + x^2) / (3x^2 – 9x + 2) is not a rational function since the numerator, sqrt(x) + x^2, is not a polynomial since the exponent of x is not an integer.

## What are not rational expressions?

A rational algebraic expression (or rational expression) is an algebraic expression that can be written as a quotient of polynomials, such as x2 + 4x + 4. An irrational algebraic expression is one that is not rational, such as √x + 4.

## Which of the following is not a rational number?

A number which can be expressed in the form p/q, q not equal to 0 is called a rational number. √2 is not a rational no.

## What are the 5 examples of rational equation?

## Which numbers are not rational functions?

In mathematics, the irrational numbers (from in- prefix assimilated to ir- (negative prefix, privative) + rational) are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

## Which one is not an irrational number?

Integers are rational numbers but not irrational. All the integers whether they are positive or negative or zero can be written in the form of p/q. Example: 2, 3 and 5 are rational numbers because we can represent them as 2/1, 3/1 and 5/1.

## Is 0.0 a rational number?

Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero.

## What makes a function a rational function?

Introduction. A rational function is one that can be written as a polynomial divided by a polynomial. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator. f(x) = x / (x – 3). So the domain of f is the set of all numbers other than 3.

## Which of the is not a polynomial function?

Terms containing fractional exponents (such as 3x+2y1/2-1) are not considered polynomials. Polynomials cannot contain radicals. For example, 2y2 +√3x + 4 is not a polynomial. A graph of a polynomial of a single variable shows nice curvature.
