 Fit three curves to data gathered from a plot The figure

Fit three curves to data gathered from a plot The figure below has three curves on it. A, B, and C. The x-axis is in log scale, the y-axis is not. It is available on CatCourses as Fall 2017 Matlab Project Plot.png 20 00 234 56780123 4 56781 Independent Variable, Use a graph reading assistant program to gather 20 or more points from each of the three curves. You can use any simple program you want. I have used WebPlotDigitizer and know that it will work for this purpose. This is to be done individually; do not share data. Write a Matlab script called PlotFit.m that fits a second-order polynomial to your data for the curves. Enter the data found from the first step directly into your script. (Most of the graph assistants will allow collection of a whole set of data points thatcathen be copied to the clipboard for use in other programs.) Also find the goodness of fit information, particularly the R2 value for the fit curve Plot your collected data points as points (use+ signs, squares, diamonds, etc., but not a line) on a plot that is log in the x-axis (not in the y-axis). Generate a set of 100x-values from 0.01 to 1 that are evenly spaced in log space. Generate the corresponding y-values using your fit curve. On the same figure that has the collected data plot, plot the fit curve. The fit curve should be a solid line of a different color than the data points.Label both axes and generate a legend. The title must have the equation (with the parameters) and R2 value found. The example below shows a third-order polynomial equation fit to one of the curves. Note that exponents in the title are superscripted
