![### 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9d5b5049-d8dd-402a-aa3b-0cfd97dc82be%2F141d8b94-8356-4c4c-a4fe-74ae0b7f9588%2Fnqvefn_processed.png&w=3840&q=75)
