Exercise 3.3.35

Answers

For the $- 1, 2, - 1$ matrix $K (9$ by 9 $)$ and constant right side $b = (10, \dots, 10)$ , the solution $x = K^{- 1} b = (45, 80, 105, 120, 125, 120, 105, 80, 45)$ rises and falls along the parabola $x_{i} = 50 i - 5 i^{2} . (A$ formula for $K^{- 1}$ is later in the text.)
