A graph crosses straight through the x-axis at a zero. That zero has multiplicity that is:
AOdd
BEven
CZero
DHalf
Answer & Solution
Correct answer: A. Odd
1. Passing through means the output changes sign.
2. A sign change needs the factor to appear an odd number of times.
3. So the multiplicity there is odd.
