### Volume of Solids of Revolution - Calculus Problem

#### Problem Statement:
Find the volumes of the solids obtained by rotating the region bounded by the curves \( y = \frac{4}{\sqrt{x}} \) and \( y = x^2 \) about the following lines. Draw the graph in each case. **All answers must be in simplified form.**

#### Subproblems:
a.) The x-axis. **Work needs to be justified.**

b.) The y-axis. **Work needs to be justified.**

c.) \( y = 2 \). **Set up but do not evaluate.**

#### Explanation:
1. **Rotating about the x-axis:**
   - Find the points of intersection of the curves \( y = \frac{4}{\sqrt{x}} \) and \( y = x^2 \).
   - Use the disk method or washer method to set up the integral that represents the volume.
   - Integrate and simplify the result.

2. **Rotating about the y-axis:**
   - Find the points of intersection of the curves.
   - Use the shell method to set up the integral that represents the volume.
   - Integrate and simplify the result.

3. **Rotating about the line \( y = 2 \):**
   - Find the points of intersection of the curves.
   - Use the washer method, adjusting the radii to account for the offset of the line \( y = 2 \).
   - Set up the integral without performing the evaluation.

#### Visualization:
- **Graphs:**
  - Draw the graphs of both equations \( y = \frac{4}{\sqrt{x}} \) and \( y = x^2 \) to identify the region bounded by them.
  - Clearly mark the axes and the lines of rotation (x-axis, y-axis, and \( y = 2 \)) on the graphs.
  - Shade the region that will be revolved to form the solid.

This structured approach breaks down the problem into manageable steps and uses visualization to aid understanding, providing a clear path to solving these types of calculus problems.
