Problem 2 (25 pts) Download the MAT file Problem2Data.mat" from Canvas. This file contains the (x, y) data from a lab experiment. Write a MATLAB script that performs the following: a. ( pty Load the MAT file into your scrpt using the following command: >load('Problem2Data.mat b. ps) Use the forward difference approach with truncation error of the order O(h) to estimate the as a scatter plot(not connected by lines). Be sure to cond derivative ar Create a plot ofx vs. a include a title and axis labels. Fit a curve of the form f (x) Axb to the second derivative calculated in part . b.. i (5 pts) Create a new vector 'x2' that contains 100 evenly-spaced points between 0 and 20, and a c. corresponding vector y2' that contains the values of f(x) at each point in x2. ii. (2pts) Superimpose a line graph ofx2 vs. y2 on top of your figure created in part b. ili (8pts) Calculate the R2 value of the curve and display it in the command window
