I have provided a detailed solution for your problem. I have also checked your partial solution. I found at two places your first order differentiation to find the minimum value was wrong. I have indicated it with red arrows. I have used different notations at some places.

Please find attached 1) Solution for the given problem

2) Your question file with some corrections.

Solution:

Since the decision variables are x1, x2 and x3, the given problem is a three-stage problem defined as follows:

s3=3x1+2x2+x3 ≥ 18

s2=3x1+2x2=s3-x3

s1=3x1=s2-2x2

Therefore the functional (recurrence) relation is

f1(s1) = min (3x12) = (s2-2x2)2

0≤x1≤s1

f2(s2) = min (3x12+x22) = min ...
