Properties of the leading term of a polynomial reveal whether the function increases or decreases continually as x values approach positive and negative infinity. If n is odd and an is positive, the function declines to the left and inclines to the right. If n is odd and an is negative, the function inclines to the left and declines to the right. If n is even and an is positive, the function inclines both to the left and to the right. If n is even and an is negative, the function declines both to the left and to the right.

A polynomial function may have zero, one, or many zeros. All polynomial functions of positive, odd order have at least one zero, while polynomial functions of positive, even order may not have a zero. Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order.

Researchers will often collect many discrete samples of data, relating two or more variables, without knowing the mathematical relationship between them. Curve fitting is used to create trend lines intended to fill in the points between and beyond collected data points. Polynomial functions are easy to use for modeling but ill-suited to modeling asymptotes and some functional forms, and they can become very inaccurate outside the bounds of the collected data. Rational functions can take on a much greater range of shapes and are more accurate both inside and outside the limits of collected data than polynomial functions. However, rational functions are more difficult to use and can include undesirable asymptotes. Introduction: Polynomial and Rational Functions and Models Free to share, print, make copies and changes.

Key terms asymptote A line that a curve approaches arbitrarily closely, as they go to infinity; the limit of the curve, its tangent "at infinity". Leading coefficient The coefficient of the leading term. Leading term The term in a polynomial in which the independent variable is raised to the highest power. zero Also known as a root, a zero is an x value at which the function of x is equal to 0.
