Using MATLAB:

a) Given the following function: f(x) = x^3 - (5x)^2 + 2^x - 1000x

Use a while loop to compute f(x) for many evenly spaced values of 0 x 20 and create a plot of the results.

b) Given the following function: (x) = 20000 log(x) 3x

Use a for loop to compute f(x) for 1 x 20 and create a plot on the same plot window as the first plot. Use a different line color and line weight for each plot.
