Please provide the AMPL syntax used. I provided the return and risk objectives in the 2nd photo and the constraints in the 1st photo. i believe to proceed with this problem you will need to minimize the risk objective and put the return objective in the constraints with the expected returns stated in the question.

return z1:0.05x1+0.1x2+0.15x3 risk z2:0.01x12+0.04x22+0.09x32+2(.012x1x2+.012x1x3+.048x2x3) Part (c): you must solve five quadratic programming problems that Minimize the risk with constraints such that expected returns must at least be 8000,8500,9000,9500,10000. respectively + other constraints given in the problem. Your generated risk-return graph should consist of 7 data points including the upper and lower bounds. Please use the same scale as is shown in the following graph template, attach your graph in the space and submit all your related AMPL files on Canvas. x1,x2,x380,000x120,000x235,000x2+x370,000x1+x2+x3=100,000x1,x2,x30 return z1:0.05x1+0.1x2+0.15x3 risk z2:0.01x12+0.04x22+0.09x32+2(.012x1x2+.012x1x3+.048x2x3) Part (c): you must solve five quadratic programming problems that Minimize the risk with constraints such that expected returns must at least be 8000,8500,9000,9500,10000. respectively + other constraints given in the problem.
