Statement
The quadratic formula can only be used when solving a quadratic equation. Cubic equations always have three real roots. The graph of a cubic function always passes through all four quadrants. The graphs of all polynomial functions must pass through at least two quadrants.
The expression
For the following exercises, use the given information about the polynomial graph to write the equation. Degree 5. Roots of multiplicity 2 at
Every cubic polynomial can be categorised into one of four types: Type 1: Three real, distinct zeros:
Type 2: Two real zeros, one repeated:
Type 3: One real zero repeated three times:
Type 4: One real and two imaginary zeros:
Experiment with the graphs of Type 4 cubics. What is the geometrical significance of
