(I am taking an online Python class. I read ahead and this is the practice assignment. Any help with coding?)

Write a program to perform a linear, 2nd-order polynomial, exponential, power-law, and logarithmic curve-fits. You will need to write a new function to find the 2nd-order polynomial coefficients (see your book and the study guide for more details). For the other models, utilize the linear least-squares regression function you wrote for Assignment 3.1. Be sure to calculate the coefficient of determination for all cases.

To compare the various curve fits, plot the data along with each of the curve-fit models on the same graph. Be sure to include a legend to distinguish the models. Upload your code as well as the plot of all the curve fits. In your submission comments, tell me which curve fit you think is the "best," and why?
