Alex and Grace noticed that a few months after the initial spraying the beetle numbers started to
increase in Model 1 and 2. They think they may need to spray the beetles again at repeated
intervals. Alex and Grace decide to look at repeated intervals of Model 1 and 2 respectively to
model this new data and see if either model gives a good fit of the data. They want these repeated
intervals to start at (n, 0)
Give general equations for Alex and Grace's Model 1 and 2 equations so that they can be
used for any real values of n. Explain how you reached your solutions.
