I need the solution in matlab code

Measurements of the fuel efficiency of a car (MPG) data with car speed (V) are given in the following table. v (mi/h) 5 15 25 35 45 55 65 75 FE (mpg) 1122 28 29.5 30 30 27 23 (a) Curve-fit the data with a second-order polynomial. Use the polynomial to estimate the fuel efficiency at 60 mi/h. Make a plot of the points and the polynomial. (b) Curve-fit the data with a third-order polynomial. Use the polynomial to estimate the fuel efficiency at 60 mi/h. Make a plot of the points and the polynomial. (c) Fit the data with linear and spline interpolations. Estimate the fuel efficiency at 60 mi/h with linear and spline interpolations. Make a plot that shows the data points and curves made of interpolated points
