End Behavior of Functions

The end behavior of a function describes how the function behaves as the input variable grows without bound (approaches positive infinity) or decreases without bound (approaches negative infinity). For polynomial functions, this behavior is dictated by the leading term, which dominates the function’s value for very large absolute values of x.

Leading Coefficient Test

The leading coefficient test is a method used to determine the end behavior of a polynomial function by examining the sign and degree of its leading term. For instance, in a polynomial with an odd degree, a negative leading coefficient indicates that the function will tend to negative infinity as x approaches positive infinity and positive infinity as x approaches negative infinity.

Polynomial Functions

A polynomial function is an expression consisting of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. These functions are continuous and smooth, and their behavior is largely determined by the term with the highest exponent, known as the leading term.
