Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

    Ah, sorry, sorry, Just realized that my explanation is completely wrong did your teacher show you how to find the R^2 value?

    well, ok, I just plugged this into my calculator, and the third answer gives me the highest R^2 value, so my best guess is the third option
