To determine the expression that the graph of the additive rule represents, we can analyze the points given: (2, 39) and (4, 41).
An additive function can be expressed in the form of
From the first point (2, 39):
- When
, , so: Therefore, the expression could be .
From the second point (4, 41):
- When
, , so: This also confirms that .
Thus, both points indicate that the expression the graph represents is:
So the final answer is: x + 37.
