m. Be careful about the units. Put the m-file and the table to your paper. Q5: Measurements of the fuel efficiency of a car FE at varios speeds v are shown in the table v(mi/h) 5 FE(mpg) 11 15 25 35 45 55 65 75 22 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 between v=5-75 mi/h with an increment of 1 mi/h. (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 between v=5-75 mi/h with an increment of 1 mi/h. (c) Fit the data with linear and spline interpolations. Estimate 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 between v=5-75 mi/h with an increment of 1 mi/h. Q6: Solve the following system of five linear equations.
