Analyze the first graph option
We observe the behavior of the first graph:
- As \(x \to -\infty\), the curve goes downwards to \(-\infty\).
- As \(x \to \infty\), the curve goes upwards to \(\infty\).
- The graph crosses the \(x\)-axis at \(x = -1\), \(x = 1\), and \(x = 5\).
- It has a local maximum at \((0, 5)\) and a local minimum at \((3, -17)\).
- This matches a standard cubic polynomial \(f(x) = (x+1)(x-1)(x-5) = x^3 - 5x^2 - x + 5\).
Analyze the second graph option
We observe the behavior of the second graph:
- As \(x \to -\infty\), the curve goes upwards to \(\infty\).
- As \(x \to \infty\), the curve goes downwards to \(-\infty\).
- This represents a cubic polynomial with a negative leading coefficient, which is the vertical reflection of the first graph.
Match with the correct choice
- The first graph correctly represents the cubic function \(f(x) = x^3 - 5x^2 - x + 5\) with positive end behavior.
- Therefore, the first option is the correct graph.

- (A) The first graph, which starts in the third quadrant, goes up through \((-1,0)\) to a local maximum at \((0,5)\), goes down through \((1,0)\) to a local minimum at \((3,-17)\), and then goes up through \((5,0)\) into the first quadrant. (Correct answer)
- (B) The second graph, which is a vertical reflection of the first graph, starting in the second quadrant and ending in the fourth quadrant.
- (C) The third graph, which shows a narrow parabola-like shape opening upwards.
