A simple way to solve a least-squares problem c A mechanism for solving discrete optimization problems d. Faster way to differentiate numerically a multivalued function 2. When fittinga straight line to the five (data) points shown in the diagram below, which line represents the least squares solution . Whenfitting a straight lin to the five (data) points shown in the diagram below, which line represents the minimax solution (i.e, minimizes the maximum error). 10 08 08 02 203 045 02 04

Explanation / Answer

2.Line b represents the least square solution.Least squares means that the overall solution minimizes the sum of the squares of the residuals made in the results of every single equation.
3.line c
