1. **State the problem:** Find the coordinates of the minimum point of the curve given by the function $$y = 2x^2(3 + x)$$.
2. **Rewrite the function:** Expand the expression to simplify differentiation.
$$y = 2x^2 \times 3 + 2x^2 \times x = 6x^2 + 2x^3$$
3. **Find the derivative:** To find critical points (potential minima or maxima), differentiate $$y$$ with respect to $$x$$.
$$\frac{dy}{dx} = \frac{d}{dx}(6x^2 + 2x^3) = 12x + 6x^2$$
4. **Set the derivative equal to zero to find critical points:**
$$12x + 6x^2 = 0$$
Factor out $$6x$$:
$$6x(2 + x) = 0$$
5. **Solve for $$x$$:**
$$6x = 0 \Rightarrow x = 0$$
$$2 + x = 0 \Rightarrow x = -2$$
6. **Determine the nature of each critical point using the second derivative:**
Second derivative:
$$\frac{d^2y}{dx^2} = \frac{d}{dx}(12x + 6x^2) = 12 + 12x$$
Evaluate at $$x=0$$:
$$12 + 12 \times 0 = 12 > 0$$ (minimum)
Evaluate at $$x=-2$$:
$$12 + 12 \times (-2) = 12 - 24 = -12 < 0$$ (maximum)
7. **Find the $$y$$-coordinate of the minimum point at $$x=0$$:**
$$y = 6(0)^2 + 2(0)^3 = 0$$
8. **Conclusion:** The minimum point is at $$(0, 0)$$.
**Final answer:** A (0, 0)
