End behavior By:Skylar Brown

What is it ? End behavior is the behavior of a graph as it reaches negative infinity or positive infinity.

Easy way to remember To determine the end behavior, follow these rules: First find the following two pieces of information from the polynomial: 1) determine if the degree (highest exponent) is odd or even 2) determine if the leading coefficient is positive or negative *The way to remember is to think of the quadratic (degree = even) and the cubic (degree = odd). Use those simple graphs to remember what the end behavior does. Degree=odd, leading coefficient = + Degree=odd, leading coefficient= - Degree=even, leading coefficient = + Degree=even, leading coefficient= - as x-> infinity, y-> infinity as x->infinity, y -> -infinity as x-> infinity, y->infinity as x-> infinity, y-> -infinity as x->-infinity, y->-infinity as x-> -infinity, y ->infinity
