### Calculating the Area of the Region Bounded by the Graphs of Given Equations

To find the area of regions bounded by the given equations, we set up and evaluate the appropriate definite integrals. Below are the specific equations and the bounded regions they describe:

1. **Problem 4:**
   \[
   y = x^3, \quad y = 9x
   \]
   Find the area of the region enclosed by these two curves.


2. **Problem 5:**
   \[
   y = x^3, \quad y = x^2
   \]
   Determine the area of the region where these two curves intersect each other and bound a closed region.

3. **Problem 6:**
   \[
   x = 0, \quad x = 1, \quad y = x^2 + 6, \quad y = x^2 + 2
   \]
   Evaluate the area of the region bounded by the vertical lines \(x = 0\) and \(x = 1\) and the two parabolic curves \(y = x^2 + 6\) and \(y = x^2 + 2\).

4. **Problem 7:**
   \[
   x = (y - 3)^4, \quad x = (y - 5)^2
   \]
   Compute the area of the region enclosed by these two equations.

For detailed solutions, refer to integral calculus methods for finding the area between curves, which often involve:

- Identifying the points of intersection.
- Setting up the definite integral with appropriate limits.
- Integrating the difference of the functions over the identified limits.

Graphical representations of these equations can help visualize the bounded regions and facilitate the setting up of the integrals.
