Matlab

Use the "polyfit" command inside the "roots" command to fit a % quadratic polynomial through the y vs x data (from #3) and then find the % the root. Give the "roots" output a name for plotting. Leave off the ";" % so you can verify that the x-values of the root make sense. % Plot the root using blue + markers, line width 2, marker size size 60 % (see the example graph.) disp('#4')
