Let's analyze the intervals you provided to see where the function \( f \) is concave up based on the graph of its derivative \( f' \).

From the graph of \( f' \), we need to find where \( f' \) is increasing, indicating that the second derivative \( f'' \) is positive, and thus the function \( f \) is concave up.

**Interval Analysis:**

1. \((-3, -2)\):
   - In this interval, \( f' \) is decreasing (the graph is sloping downwards), so \( f \) is concave down.

2. \((-2, -1)\):
   - In this interval, \( f' \) is increasing (the graph is sloping upwards), so \( f \) is concave up.

3. \((-3, -1)\) and \((1, 3)\):
   - \((-3, -1)\): This includes both the concave down interval \((-3, -2)\) and the concave up interval \((-2, -1)\), so it is partially correct.
   - \((1, 3)\): In this interval, \( f' \) is decreasing (the graph is sloping downwards), so \( f \) is concave down.

4. \((-1, 1)\) and \((3, 4)\):
   - \((-1, 1)\): In this interval, \( f' \) is decreasing (the graph is sloping downwards), so \( f \) is concave down.
   - \((3, 4)\): In this interval, \( f' \) is increasing (the graph is sloping upwards), so \( f \) is concave up.

**Correct Intervals:**
- Based on the analysis, the correct intervals where \( f \) is concave up are:
  - \((-2, -1)\)
  - \((3, 4)\)

Thus, the correct answer from the provided choices is:
- \((-2, -1)\) and \((3, 4)\)
