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.
That's the definition of a "rational function". You simply divide a polynomial by another polynomial. The result is called a "rational function".
A rational function is the quotient of two polynomial functions.
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.
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.
It is any function which can be written as the ratio of two polynomial functions.

Yes, ( \frac{2x}{3} ) is a rational function. A rational function is defined as the ratio of two polynomials, and in this case, the numerator ( 2x ) is a polynomial of degree 1, while the denominator ( 3 ) is a constant polynomial (degree 0). Since both the numerator and denominator are polynomials, ( \frac{2x}{3} ) qualifies as a rational function.
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".
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.

Well, "non-polynomial" can be just about anything; presumably you mean a non-polynomial FUNCTION, but there are lots of different types of functions. Polynomials, among other things, have the following properties - assuming you have an expression of the type y = P(x):* The polynomial is defined for any value of "x". * The polynomial makes is continuous; i.e., it doesn't make sudden "jumps". * Similarly, the first derivative, the second derivative, etc., are continuous. A non-polynomial function may not have all of these properties; for example: * A rational function is not defined at any point where the denominator is zero. * The square root function is not defined for negative values. * The first derivative (i.e., the slope) of the absolute value function makes a sudden jump at x = 0. * The function that takes the integer part of any real number makes sudden jumps at all integers.
