Question
using the following graph, I have to sketch the graph of the derivative function M’(t) and state during which years was the derivative negative in interval notation.
**Graph Analysis for Educational Website**

***Description:***

This graph depicts the variation of an unknown variable \( M \) over time, represented by \( t \). The time span covers from the year 1960 up to the year 2000.

**Axes:**

- **Y-Axis (Vertical):**
  - Label: \( M \)
  - The values range approximately from 25 to just above 27.
  - There is a break near the bottom, indicating that the portion below 25 is not shown for this graph.

- **X-Axis (Horizontal):**
  - Label: \( t \)
  - The timeline begins at 1960 and ends at 2000.
  - Key years (1960, 1970, 1980, 1990, 2000) are marked for reference, evenly spaced along the axis.
  
***Graph Line:***

- The graph line starts in 1960 with a value slightly above 25.
- Between 1960 and 1970, the value of \( M \) rises to around 27.
- There is a slight decline following this peak, stabilizing at a value close to 26 in the period between 1970 and 1980.
- Post-1980, the value gradually increases again, surpassing 27 between 1990 and 2000, and then it seems to level off.

***Interpretation:***

The graph illustrates that the variable \( M \) experienced fluctuations over the observed period. After a rise from 1960 to 1970, it dipped before experiencing a gradual increase again from 1980 to 2000. Throughout the entire period, \( M \) remained within a relatively narrow band around 25 to 27, indicating minor variations relative to the chosen scale of measurement.
