(1) Plot linear function, power fuction and exponential fuction against these data. Plot both data points (with 'o') and fuction line ('-') on the same plot. keep the three plots on the same plot. (use subplot). Decide which function best fits these data
(2) Find out the coefficients m and b of the function you decided from (1) and plot the original data with this function on the same plot.
