You can use linear regression to calculate each hypothesis.
(since linear regression is basically analytical formula for minimizing mean square error).

Also, you can confirm if your g_bar from simulation makes sense by calculate it directly. (calculate expectation of the hypothesis from each (x1,x2) over [-1,1] x [-1,1] ). This involves two integrals but you can plug in the expression to wolfram or mathematica.
