Question
A function is continuous on the closed interval \([-3, 3]\) such that \(f(-3) = 4\) and \(f(3) = 1\). The functions \(f'(x)\) and \(f''(x)\) have the properties given in the table below.

| \(x\)             | \(f'(x)\)    | \(f''(x)\)   |
|-------------------|-------------|-------------|
| \(-3 < x < -1\)   | Positive    | Positive    |
| \(x = -1\)        | Fails to exist | Fails to exist |
| \(-1 < x < 1\)    | Negative    | Positive    |
| \(x = 1\)         | Zero        | Zero        |
| \(1 < x < 3\)     | Negative    | Negative    |

Questions:
a. What are the x-coordinates of all absolute maximum and minimum points of \(f\) on the interval \([-3, 3]\)? Justify your answer.

b. What are the x-coordinates of all points of inflection on the interval \([-3, 3]\)? Justify your answer.

c. On the axes provided, sketch a graph that satisfies the given properties of \(f\).

**Graph Sketching:**

- The graph should show increasing behavior on \((-3, -1)\) because \(f'(x) > 0\).
- \(f(x)\) has a sudden change at \(x = -1\) where \(f'(x)\) fails to exist.
- The graph should show decreasing behavior on \((-1, 1)\) since \(f'(x) < 0\), but with positive concavity (\(f''(x) > 0\)).
- At \(x = 1\), \(f'(x) = 0\) and \(f''(x) = 0\), indicating a potential inflection point.
- The graph continues to decrease on \((1, 3)\) with negative concavity (\(f''(x) < 0\)).

These insights can be used to help sketch the function \(f(x)\) accurately.
