State an R function that can be used to read a csv file. (1 mark) b) The following information show various cars with different aspects of performance, including miles/gallon (mpg), number of cylinders (cyl), displacement (disp), rear axle ratio (drat) and weight (wt). Based on these information, answer the following questions.
