Key Concepts

Leading Coefficient

The leading coefficient in a polynomial function is the coefficient of the term with the highest degree. It has a significant impact on the end behavior of the graph. When it is negative, particularly in an even degree polynomial, it indicates that the ends of the graph will both point downward.

Degree of the Polynomial

The degree of a polynomial is the highest exponent in its expression. The degree determines several key characteristics of the graph, such as the maximum number of turning points and the general shape of the function. Even-degree polynomials, for instance, have end behaviors where both ends of the graph move in the same direction.

End Behavior

End behavior refers to the behavior of a polynomial function as x approaches positive or negative infinity. This behavior is controlled by the leading term, meaning the combination of the leading coefficient and its corresponding power. For example, an even-degree polynomial with a negative leading coefficient will have both ends of its graph tending downwards.
