Agree Disagree Justification
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 $$x2 >4$$ is only true if $$x>2$$. If you know the instantaneous rates of change for a function at $$x = 2$$ and $$x = 3$$, you can predict fairly well what the function looks like in between.
