• Looking at the data, determine for which points an exponential function fits this data, and for which points the growth is not exponential.
• Because patterns change in real life, to create a true function to represent these data, you need to piece together two equations, called a piecewise function: you'll need to clearly state the domain for which each equation applies. Find these two equations of best fit either by hand or with a graphing calculator, making sure that you're finding two (or more) separate equations for the different sections of the graph.
