What is the general form of a cubic function?

Back

y = ax^3 + bx^2 + cx + d, where a ≠ 0.

Front

What is the leading coefficient of the cubic function y = 2x^3 - 3x^2 + x - 5?

Back

2

Front

What is the end behavior of the cubic function y = -x^3?

Back

As x → ∞, y → -∞; As x → -∞, y → ∞.

Front

What is the significance of the x-intercepts in a cubic function?

Back

They represent the points where the graph intersects the x-axis.

Front

What does the term 'turning points' refer to in cubic functions?

Back

Points where the graph changes direction (local maxima or minima).

Front

How many turning points can a cubic function have?

Back

A cubic function can have at most 2 turning points.
