If the graph of a polynomial crosses the x-axis at x=-1, is the multiplicity of that zero even or odd?

Odd

400

If you are looking at a graph and it bounces off the x-axis at x=4, what do you know about the multiplicity of that zero?

It must be an even multiplicity (like 2, 4, 6)

Why is the value of a Vertical Asymptote excluded from the domain of the function?

Because it makes the denominator 0 (ERROR)
