Extracted text: For the same data given for 7_1, -4 -2 01 2 a) Plot the data points with a circle marker (MATLAB). y -10 3 8 25 52 36 b) Plot the unique interpolating polynomial (passes exactly through each point) and print the equation of the polynomial (in the form y = a, x^+ an-1X^-1 + .. + a;x + ao) to the screen using fprintf. Don't use polyfit & polyval for this problem; use the backslash on the Van der Monde matrix & construct the function handle and use fplot. c) Plot the linear splines between each pair of points using interpl. d) Plot the "not-a-knot" cubic spline using interpl 3.
