How is a rational function the ratio of two polynomial functions?

That's the definition of a "rational function". You simply divide a polynomial by another polynomial. The result is called a "rational function".


How does my knowledge of polynomial function prepare me to understand rational function?

A rational function is the quotient of two polynomial functions.


What is a rational equation or rational function?

It is any function which can be written as the ratio of two polynomial functions.


What are some similarities between rational functions and polynomial function?

Rational functions and polynomial functions both involve expressions made up of variables raised to non-negative integer powers. They can have similar shapes and behaviors, particularly in their graphs, where they may exhibit similar end behavior as the degree of the polynomial increases. Additionally, both types of functions can be manipulated algebraically using addition, subtraction, multiplication, and division, although rational functions can include asymptotes due to division by zero, which polynomial functions do not have. Both functions can also be analyzed using techniques such as factoring and finding roots.


How could I compare and contrast rational and polynomial function properties?

Rational functions are ratios of two polynomial functions, which means they can exhibit unique behaviors such as asymptotes and discontinuities, while polynomial functions are continuous and smooth curves without breaks. Both types can have similar characteristics, such as degree and leading coefficient, which influence end behavior and intercepts. However, rational functions can approach vertical and horizontal asymptotes, while polynomial functions do not; they continue to rise or fall indefinitely. Ultimately, understanding these differences helps in analyzing their graphs and behaviors in various contexts.


What are the properties of rational functions?

Such functions are defined as one polynomial divided by another polynomial. Their properties include that they are defined at all points, except when the denominator is zero. Also, such functions are continuous at all points where they are defined; and all their derivatives exist at any point where they are defined.For more details, I suggest you read the Wikipedia article - or some other source - on "Rational function".


What is rational algebra expression?

Basically, a rational expression is one that can be written as one polynomial, divided by another polynomial.


How do you factor a polynomial with the equation of 6A2 - B 2?

What is a rational function?

In mathematics, a rational function is any function which can be written as the ratio of two polynomial functions. Neither the coefficients of the polynomials nor the values taken by the function are necessarily rational numbers.In the case of one variable, , a function is called a rational function if and only if it can be written in the formwhere and are polynomial functions in and is not the zero polynomial. The domain of is the set of all points for which the denominator is not zero, where one assumes that the fraction is written in its lower degree terms, that is, and have several factors of the positive degree.Every polynomial function is a rational function with . A function that cannot be written in this form (for example, ) is not a rational function (but the adjective "irrational" is not generally used for functions, but only for numbers).An expression of the form is called a rational expression. The need not be a variable. In abstract algebra the is called an indeterminate.A rational equation is an equation in which two rational expressions are set equal to each other. These expressions obey the same rules as fractions. The equations can be solved by cross-multiplying. Division by zero is undefined, so that a solution causing formal division by zero is rejected.


What are the Basic concepts of rational function?

Thee basic concept is that an rational function is one polynomial divided by another polynomial. The coefficients of these polynomials need not be rational numbers.


What is the difference between rational and polynomials?

A polynomial function is simply a function that is made of one or more mononomials. For example 4x^2+3x-5 A rational function is when a polynomial function is divided by another polynomial function.


Can a polynomial be no rational zeros but have real zeros?

Yes, a polynomial can have no rational zeros while still having real zeros. This occurs, for example, in the case of a polynomial like (x^2 - 2), which has real zeros ((\sqrt{2}) and (-\sqrt{2})) but no rational zeros. According to the Rational Root Theorem, any rational root must be a factor of the constant term, and if none exist among the possible candidates, the polynomial can still have irrational real roots.
