Key Concepts

Polynomial Functions

Polynomial functions are expressions consisting of variables and coefficients combined using only addition, subtraction, multiplication, and non-negative integer exponents. Their graphs are smooth, continuous curves that can have varying shapes depending on the degree of the polynomial and the coefficients involved.

Degree of a Polynomial

The degree of a polynomial is the highest power of the variable that appears in the expression, and it plays a crucial role in determining the overall behavior of the function. For instance, a fifth-degree (quintic) polynomial can exhibit up to four turning points and typically has an odd degree, meaning its ends will extend in opposite directions.

Leading Coefficient Test

The leading coefficient is the coefficient of the highest-degree term in a polynomial, and it, along with the degree, determines the end behavior of the function. For polynomials with an odd degree, if the leading coefficient is positive, as x approaches infinity the function goes to infinity and as x approaches negative infinity the function goes to negative infinity, and vice versa if the coefficient is negative.

End Behavior

End behavior describes how the function behaves as the input values become very large or very small. In the context of polynomial functions, the end behavior is governed by the degree and the leading coefficient, giving insight into the general shape of the graph at extreme values of x.
