Question

What is the average rate of change of the function represented by the table between x = 1 to x = 3 months, and what does the average rate represent

Answer 1

The average rate of change can also be called the slope. When they say x = 1 and x=2 you have to find the corresponding points on your graph where for (1,y) and (3,y) with that you can use the slope formula \[\frac{ Y _{?}^{} - Y _{1}^{}}{X _{?}^{} - X _{1}^{} }\]
Where the 2 means the x or y value for your second point and 1 means the x or y value of your first point.
