Transcribed Image Text:### Graph Analysis Exercise
Use the given graph of \( f \) over the interval (0, 7) to find the following:
**Graph Description:**
- The graph displayed on a grid shows a curve indicating how the function \( f \) behaves within the interval (0, 7). The x-axis ranges from 0 to 7, and the y-axis ranges from -1 to 3. The curve initially decreases, then increases, decreases again, and finally increases within this interval.
**Tasks:**
(a) **The open intervals on which \( f \) is increasing.**
*Answer:* \((0,1), (3,7)\) ✔️
(b) **The open intervals on which \( f \) is decreasing.**
*Answer:* \((1,3)\) ✔️
(c) **The open intervals on which \( f \) is concave upward.**
*Answer:* \((2,5)\) ❌
(d) **The open intervals on which \( f \) is concave downward.**
*Answer:* \((0,3)\) ❌
(e) **The coordinates of the points of inflection.**
**Explanation:**
- The increasing intervals are those where the graph moves upwards.
- The decreasing intervals are those where the graph moves downwards.
- Concavity indicates the direction the graph curves: upward or downward.
- Points of inflection are points where the graph changes concavity.
