Step-by-Step Analysis
We are given two forms of the same cubic polynomial: y = 12(x+1)(x+2)(x-4) and y = (1/2)(x+1)(x+2)(x-4). The graphs shown in the options all represent a cubic with roots at x = -2, -1, and 4, since those are the zeros of the factored form. When comparing the two expressions, the only difference is the overall vertical scale (the leading coefficient).
- Option a: Think about how a larger leading coefficient affects the graph. A coefficient as large as 12 would make the curve much steeper (steeper growth away from the x-axis) than a coefficient of 1/2. If this option shows ......Login to view full explanationLog in for full answers
