Question: Given points in R 2 , let S = conv {p 1 ; p 2 ; p 3 }. For each linear functional f, find

Given points P = [6].P = [3], and ps = [-2] P2 P3in R2, let S = conv {p1; p2; p3}. For each linear functional f, find the maximum value m of f on the set S, and find all points x in S at which f (x) = m.

a. f (x1,x2) = x1 – x2 

b. f (x1, x2) =  x1 + x2

c. f (x1; x2) = 3x1 + x2

P = [6].P = [3], and ps = [-2] P2 P3
