Must use R programming to complete this problem

Data set is in package faraway in R programing

please list the code as well

2. Use the cars data (not in the "faraway" package) with distance as the response and speed as the predictor. (a) Plot distance against speed (b) Show a linear fit to the data on the plot. (c) Show a quadratic fit to the data on the plot. (d) Now use sqrt dist) as the response and fit a linear model. Show the fit on the same plot
