MATLAB: The standard air density, D(average measurements made), at different height, h, from sea level up to a height of 33km is given below.

h(km)	0	3	6	9	12	15
D(kg/m^3)	1.2	0.91	0.66	0.47	0.31	0.19
h(km)	18	21	24	27	30	33
D(kg/m^3)	0.12	0.075	0.046	0.029	0.018	0.011

a. Make the following four plots of the data points (density as a function of height):

(1) both axes with linear scale; (2) h with log axis, D with linear axis; (3) h with linear axis, D with log axis; (4) both log axes. According to the plots choose a function (linear, power, exponential, or logarithmic) that best fits the data points and determine the coefficients of the function.

b. Plot the function and the points using linear axes.
