Write a polynomial function of least degree that has rational coefficients

The third term is a constant. For more details, see homogeneous polynomial. A real polynomial function is a function from the reals to the reals that is defined by a real polynomial. Similarly, an integer polynomial is a polynomial with integer coefficients, and a complex polynomial is a polynomial with complex coefficients.

The argument of the polynomial is not necessarily so restricted, for instance the s-plane variable in Laplace transforms.

To do this, p points are chosen from the data set, with p denoting the number of parameters in the rational model. For fitting rational function models, the constant term in the denominator is usually set to 1.

A real polynomial is a polynomial with real coefficients. The polynomial in the example above is written in descending powers of x. Thus, rational functions can easily be incorporated into a rational function model.

Polynomial

Because the degree of a non-zero polynomial is the largest degree of any one term, this polynomial has degree two. Rational function models are moderately easy to handle computationally. Rational function models have the following advantages: A polynomial in one indeterminate is called a univariate polynomial, a polynomial in more than one indeterminate is called a multivariate polynomial.

Rational function models have excellent asymptotic properties. In polynomials with one indeterminate, the terms are usually ordered according to degree, either in "descending powers of x", with the term of largest degree first, or in "ascending powers of x".

This in turn means that fewer coefficients will be required compared to the polynomial model. The names for the degrees may be applied to the polynomial or to its terms. Rational function models can take on an extremely wide range of shapes, accommodating a much wider range of shapes than does the polynomial family.

It is common, also, to say simply "polynomials in x, y, and z", listing the indeterminates allowed. The commutative law of addition can be used to rearrange terms into any preferred order.

The term "quadrinomial" is occasionally used for a four-term polynomial. Polynomials of degree one, two or three are respectively linear polynomials, quadratic polynomials and cubic polynomials.

It may happen that this makes the coefficient 0. The rational function model is a generalization of the polynomial model: The polynomial 0, which may be considered to have no terms at all, is called the zero polynomial. These notions refer more to the kind of polynomials one is generally working with than to individual polynomials; for instance when working with univariate polynomials one does not exclude constant polynomials which may result, for instance, from the subtraction of non-constant polynomialsalthough strictly speaking constant polynomials do not contain any indeterminates at all.

Rational function models have better interpolatory properties than polynomial models. Rational functions can be either finite or infinite for finite values, or finite or infinite for infinite x values.Write a polynomial function ff of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.
