Question
Find the formula of f(x), a polynomial function of a last degree
The image contains a graph plotted on a Cartesian plane. 

### Description of the Graph:

- **Axes**: 
  - The horizontal axis (x-axis) ranges approximately from -10 to 10.
  - The vertical axis (y-axis) ranges approximately from -10 to 10.
  
- **Curve**: 
  - The graph displays a blue curve, which appears to represent a cubic polynomial function due to its distinctive S-shape. 
  - The curve decreases, crosses the x-axis at around x = -2, reaches a minimum, then increases and crosses the x-axis again at around x = 2. It continues rising sharply as x increases.

- **Intercepts and Critical Points**:
  - The curve intersects the x-axis near x = -2 and x = 2, suggesting these are roots of the function.
  - There is a visible turning point, possibly a local minimum, near x = 0.

- **Grid**: 
  - The background features a dot grid, indicating increments of 1 unit on both axes, which helps in estimating the position of the curve more accurately.

This graph may be used to discuss topics such as the behavior of polynomial functions, their roots, turning points, and general curve sketching.
