To understand the change in the stock's value, we analyze the information provided:
- The first change was an increase of 3 points, which can be represented as +3 points.
- The next day, the change was represented as –6 points, indicating a decrease of 6 points.
To find the overall change, we can add the two changes:
- First change: +3 points
- Second change: -6 points
Calculating this gives us:
3 points - 6 points = -3 points
The overall change in the stock's value is a decrease of 3 points.
Therefore, the correct description of the change in the stock's value is:
