4 cards from this section. Quick, good the night before a test.
What are the possible rational roots for f(x) = x³ - 6x² + 11x - 6?
Look at the factors of the constant term and the leading coefficient.
Find the y-intercept of the function f(x) = 2(x - 3)(x + 1)(x + 2).
Evaluate f(0) to find the y-intercept.
What degree does a cubic function have?
Think about the power of x in the function f(x) = ax³ + bx² + cx + d.
True or False: A cubic function can have more than three real roots.
Recall the definition of a cubic function.
Given f(x) = x³ + 3x² – 4x – 12, determine all roots and sketch the graph.
Check rational roots such as ±1, ±2, and apply synthetic division.
Create a real-world context that can be modeled with a cubic function. Describe the situation and derive a cubic function representing it.
