1. Comparing L2 and L1
A. Let S be the set of points in the (x₁, x₂) plane that minimizes the function f(x₁, x₂) =
(4x₁ + 3x₂ - 10)². Describe Sf using set notation, and draw a graph in the
(x₁, x₂) plane that shows the set Sf (Hint: the set is a line).
B. From (A) we know there is more than one pair (x₁, x₂) that minimizes f(x₁,x₂). Find
the point (x₁, x₂) in Sƒ that minimizes the length of the vector (x₁, x₂) (note the length
of the vector is the distance between (0,0) and the point (x₁, x₂).
