Record any similarities and differences between your predicted graph and the graph of actual data

There is no graphs attached hence I will provide a rundown of possible discussion points.

Differences/ similarities in trendline data, increase/ decrease/no change in trendline for a certain range of data on the x axis and the degree of change observed (how much increase/ decrease).

hope this : -)
