The following function defines a curve with several unequal minima over the interval: 2 ≤ x ≤ 20,

Develop a MATLAB script to (a) plot the function over the interval. Determine the minimum (b) with fminbnd and (c) by hand with golden-section search with a stopping criterion corresponding to three significant figures. For (b) and (c), use initial guesses of [4, 8].
