**Finding the Area of the Region**

To find the area of the region, refer to the Examples 1, 2, 3, and 4.

Given Functions:
- \( f(x) = 7(x^3 - x) \)
- \( g(x) = 0 \)

**Graph Explanation:**

The graph shows two functions, \( f(x) \) and \( g(x) \):

1. **Function \( f(x) \)**:
   - This is a cubic function represented by \( f(x) = 7(x^3 - x) \).
   - It passes through the x-axis and creates a wave-like shape with peaks and valleys.

2. **Function \( g(x) \)**:
   - This is a constant function, \( g(x) = 0 \), which is the x-axis itself.

**Shaded Region:**
- The region shaded in blue represents the area between the curve of \( f(x) \) and the x-axis (where \( g(x) = 0 \)).
- The shaded area is between approximately \( x = -1.7 \) to \( x = 1.4 \).

**Objective:**
- Calculate the area of this region by integrating the function \( f(x) \) over the specified interval where it lies above the x-axis.
