Learn how to analyze end behavior of polynomial functions based on degree and leading coefficient sign. Practice homework included.
E N D
End Behavior • The end behavior of a function’s graph is the behavior of the graph as x approaches positive infinity or negative infinity. • End behavior of a polynomial function is determined by the degree and sign of its leading coefficient.
Degree: Odd • Leading Coefficient: Positive y = x3
Degree: Odd • Leading Coefficient: Negative y = -x5
Degree: Even • Leading Coefficient: Positive y = x2
Degree: Even • Leading Coefficient: Negative y = -x4
