Cherry Blossoms - Logarithmic Regression

Adjust the sliders to fit the logarithmic function f(x) to the Cherry Blossoms data. Record your best-fit function. Repeat with your a different type of function that you define, as g(x). g(x) is currently turned off and defined as g(x) = 0. Use the same a,b,c,d sliders as parameters in your function, then record your best-fit function.
