Question

The graph of a function f (x) is shown. List the letter(s) of the point(s) at which f '(x)< 0 and f ''(x)> 0.

This image presents a graph on an xy-coordinate plane, useful for educational purposes to explain concepts like graphs of functions, data points, and trends in mathematical contexts. 

### Graph Explanation:

- **Axes**: 
  - The horizontal axis is labeled 'x.'
  - The vertical axis is labeled 'y.'

- **Data Points**:
  - The graph includes five key data points labeled **A, B, C, D,** and **E**.
  - Each point is represented by a black dot.

- **Curve**:
  - A smooth blue curve connects these points sequentially in the order A → B → C → D → E.
  - This curve illustrates the relationship or trend between these points in the context of the data provided.

### Points Description:
- **Point A**: Located furthest left on the graph, contributing to an initial understanding of the curve's starting position.
- **Point B**: Situated below Point A, indicating a downward movement.
- **Point C**: Above and to the right of Point B, showing an upward progression.
- **Point D**: To the right and slightly above Point C, suggesting a continued upward trend albeit more gradual.
- **Point E**: To the right of Point D, showing a slight downward curve, indicating a peak followed by a minor decline.

This diagram can be utilized to understand polynomial functions, trends in data science, and basic principles of calculus, including maxima, minima, and points of inflection.
