Problem 1. The plot below shows a number of noisy (x, y) datapoints and a nonlinear model y = f(x) fit to the data by linearization and least squares. 10 10³ 10⁰ 10-3 10-² 10-1 10⁰ X ● (x,y) -least-squares fit 10¹ 10² (a) What is the appropriate functional form of the nonlinear model, given this plot? Your answer should be some function y = f(x) with one or more unknown constants in f. (b) Determine the values of the constants from the least-squares fit shown in the plot. (c) Plug the constants into the formula from (a) to give y = f(x) as an explicit function. (d) Suppose you have the noisy data points as vectors x and y in Julia or Matlab. Write a few lines of code that would determine the values of the constants from a least-squares fit and generate a function for the model y = f(x).
