Question

When I took the integral with respect to Y, I got -24x^2(x^3-2x-4). Then using this for the integral with respect to X from -2 to 0, I got 320. But the system says this is not the correct value.  Could you please print clearly or type the necessary steps to take to solve the problem?  Thank you.

### Double Integral and Region of Integration

**Problem Statement:**
Sketch the region of integration and evaluate the following integral:
\[
\iint_R 12x^2 \, dA
\]
where \( R \) is bounded by \( y = 0 \), \( y = 4x + 8 \), and \( y = 2x^3 \).

---

#### Region of Integration

**Task:**
Sketch the region of integration. Choose the correct graph from the options provided.

**Options:**

- **Option A:**
  - Graph of the region bounded by the curves.
  - The region is shaded, and the boundaries \( y = 0 \), \( y = 4x + 8 \), and \( y = 2x^3 \) are shown.
  - This option does **not** correctly represent the bounded region.
  
- **Option B:**
  - The shaded region appears incorrect.
  
- **Option C:**
  - Another incorrect depiction of the region.
  
- **Option D:**
  - This option correctly shows the bounded region, which is shaded in blue.
  - The boundaries include \( y = 0 \) along the x-axis, and the curves \( y = 4x + 8 \) and \( y = 2x^3 \).

**Correct Choice:**
- **Option D** is the correct graph.

#### Evaluation of the Integral

**Task:**
Evaluate the integral
\[
\iint_R 12x^2 \, dA
\]

**Simplifying:**
- After sketching the correct region (as indicated in Option D), you would typically set up the double integral with appropriate limits derived from the boundaries given:
  - \( y = 0 \)
  - \( y = 4x + 8 \)
  - \( y = 2x^3 \)

---

**Answer Box:**
- Solve the integral and provide the result here after performing integration steps:
  
\[
\iint_R 12x^2 \, dA = \boxed{}
\]

---

This problem requires you to understand the process of setting up a double integral and visually identifying the correct region of integration. After this, performing the integration based on the limits will give the final value.
