Describing End Behavior Using Limit Notation Youtube Math Algebra 2 Polynomial graphs End behavior of polynomials. . The end behavior of a function is the behavior of the graph of the function f x as x approaches positive infinity or negative infinity. F x as x f x as x. There are two important markers of end behavior. This is determined by the degree and the leading coefficient of a polynomial function. The end behavior of a function is the behavior of the graph of the function f x as x approaches positive infinity or negative infinity. When we evaluate limits of a function as x goes to infinity or minus infinity we are examining something called the end behavior of a limit. When becomes greater and greater we say tha...
