Exploring Zeros and End Behavior of Factored Polynomials

The video tutorial explains how to determine the zeros, multiplicities, degree, and end behavior of a polynomial function given in factored form. It covers identifying zeros by setting each factor to zero, calculating multiplicities based on exponents, finding the degree by analyzing the leading term, and understanding end behavior using the leading coefficient and degree. The tutorial also includes graphing techniques to visualize these concepts.

What are the zeros of a polynomial function?

• The points where the function has a minimum

• The points where the function has a maximum

• The x-values where the function value is zero

• The y-values where the function is undefined
