16. Given A=123234345,y1=6912,y2=569 (a) Show that Ax=y1 has an infinite number of solutions parameterized by 1 free variable. Choose two different values of this variable, and generate two different solution vectors x1 and x2. Show by direct substitution that Axi=y1,i=1,2. (b) Show that Ax=y2 does not have any solutions, but it does have a 1-parameter family of least-squares solutions. Calculate the min-norm solution x1 and any other solution x2 and show that they yield the same error: Ax1y2=Ax2 y2
