What is confusing odd and even degree end behaviour?Show answer
Even degree polynomials have both ends going the same direction; odd degree polynomials have opposite directions.
What is treating a double root as just one root?Show answer
A double root counts twice when counting roots with multiplicity and produces touch-and-turn behaviour rather than crossing.
What is forgetting the sign of the leading coefficient?Show answer
Negative leading coefficient flips the graph vertically.
What is including more turning points than degree allows?Show answer
A polynomial of degree $n$ has at most $n - 1$ turning points.
