Let's go through the solution step by step for the function \( G(x) = x^4 + 2x^3 - 3x^2 - 4x \):

1. **Critical Points (First Derivative = 0)**:
   The first derivative is:
   \[
   G'(x) = 4x^3 + 6x^2 - 6x - 4
   \]
   Setting \( G'(x) = 0 \), we find the critical points:
   \[
   x = -2, \quad x = -\frac{1}{2}, \quad x = 1
   \]

2. **Second Derivative (Concavity and Inflection Points)**:
   The second derivative is:
   \[
   G''(x) = 12x^2 + 12x - 6
   \]
   Setting \( G''(x) = 0 \) to find the second-order critical points (possible inflection points):
   \[
   x = -\frac{1}{2} + \frac{\sqrt{3}}{2}, \quad x = -\frac{1}{2} - \frac{\sqrt{3}}{2}
   \]
   These are the points where the concavity changes, indicating inflection points.

3. **Intervals of Monotonicity**:
   By analyzing the sign of \( G'(x) \), we can determine where the function is increasing or decreasing:
   - Increasing on intervals where \( G'(x) > 0 \).
   - Decreasing on intervals where \( G'(x) < 0 \).

4. **Concavity and Points of Inflection**:
   Using the second derivative \( G''(x) \):
   - The function is **concave up** where \( G''(x) > 0 \).
   - The function is **concave down** where \( G''(x) < 0 \).
   - The **inflection points** occur where \( G''(x) = 0 \), at \( x = -\frac{1}{2} + \frac{\sqrt{3}}{2} \) and \( x = -\frac{1}{2} - \frac{\sqrt{3}}{2} \).

Let me now plot the graph for you.It seems like I can’t do more advanced data analysis right now. Please try again later. 

However, based on the earlier analysis:

1. **Critical Points** are at \( x = -2 \), \( x = -\frac{1}{2} \), and \( x = 1 \).
2. **Second-order critical points** (possible inflection points) are approximately \( x = -0.5 \pm \frac{\sqrt{3}}{2} \).
3. **Intervals of monotonicity** (increasing or decreasing behavior) and **concavity** can be explored further based on these derivatives.

Feel free to ask if you have any other questions or need further clarifications! Here are some related problems you could explore:

1. How do you determine whether a critical point is a local minimum, maximum, or neither?
2. How do you find intervals of increasing and decreasing functions using the first derivative test?
3. What is the geometric significance of an inflection point on a graph?
4. How can second derivative information be used to sketch a graph?
5. How do we apply the concavity test in graph analysis?

**Tip**: When sketching a graph manually, start by plotting critical points and inflection points, then use intervals of monotonicity and concavity to guide the curve's shape.
