Label the zeros, multiplicity, and determine degree and LC from a graph

The video tutorial covers the concept of zeros in a polynomial, explaining them as X intercepts and listing them. It discusses the concept of multiplicity, how it affects the graph's behavior, and differentiates between even and odd multiplicities. The tutorial then moves on to determining the degree and leading coefficient of a polynomial, explaining the relationship between turning points and degree. Finally, it demonstrates how to write a polynomial in factored form, considering the multiplicity of zeros.

What does it mean if a graph crosses the x-axis at a zero?

What is the significance of imaginary or complex zeros in relation to real zeros?

How can you identify if the leading coefficient of a polynomial is positive or negative?
