What is the degree of a cubic function?
Look at the highest power of 𝑥.
Can a cubic function have two turning points?
Think about how many times the graph can change direction.
What is the maximum number of x-intercepts a cubic function can have?
Think about the roots of the equation.
True or False: The end behavior of a cubic function is influenced only by the x-coefficients.
Consider the nature of the leading term in polynomial functions.
Given the cubic function 𝑓(𝑥) = 4𝑥³ - 9𝑥² + 2, find the x-intercepts and sketch the function, noting all turning points.
Try factoring or using the Rational Root Theorem.
If the leading coefficient of a cubic function is negative, describe the end behavior of the graph and its implications for turning points.
