Polynomial Equation
1. The problem asks us to identify the equation of a polynomial $p(x)$ based on the shape and roots of its graph.
2. The polynomial's roots are at $x = 0$, $x = 3$, and $x = -\frac{7}{2}$ from the factors given: $x$, $(x-3)$, and $(2x+7)$.
3. Observing the graph's behavior at the roots helps us determine the powers of each factor:
- At $x=0$, the graph crosses the x-axis, indicating an odd multiplicity (likely power 1).
- At $x=3$, the graph shows a turning point, suggesting a repeated root (power 2).
- At $x=-\frac{7}{2}$, the graph touches or crosses the axis, combined with its behavior indicates power 1 or 2.
4. The graph shows a flattened point near $x=3$, a key feature of a squared factor.
5. Among the given choices:
- Option A: $p(x) = x(x-3)(2x+7)^2$ (single root at 3, squared at -7/2)
- Option B: $p(x) = x^2(x-3)(2x+7)$ (double root at 0, single root at 3 and -7/2)
- Option C: $p(x) = x(x-3)^2(2x+7)^2$ (squared roots at both 3 and -7/2)
- Option D: $p(x) = x(x-3)^2(2x+7)$ (squared root at 3, single roots at 0 and -7/2)
6. The graph indicates a squared factor at $x=3$ and single at $x=0$ and $x=-\frac{7}{2}$.
7. Therefore, option D, $p(x) = x(x-3)^2(2x+7)$, matches the graph's shape and roots behavior.
Final answer:
$$p(x) = x(x - 3)^2(2x + 7)$$
