4.4 Zeros, multiplicity and end behavior
Unit 4 · Polynomials and polynomial functions
Ideas in this lesson
Solve a factored polynomial
Set each factor equal to zero and list each distinct real solution once.
Interpret multiplicity
At a zero of odd multiplicity the graph crosses the axis; at a zero of even multiplicity it touches and turns.
Predict end behavior
The leading coefficient and degree determine the behavior of the two ends.
