Unformatted text preview: 1 Problem 4 Attempt to solve the systemx 1 + 3 x 22 x 3 = 4 ,2 x 1 + 7 x 25 x 3 = 9 ,5 x 1 + 19 x 214 x 3 = 24 . using Gaussian elimination and explain why this system must have innitely many solutions. Problem 5 By solving a 3 3 system, nd the coecients in the equation of the parabola y = + x + x 2 that passes through the points (1 , 1), (2 , 2), and (3 , 0). Problem 6 Explain why a linear system can never have exactly two dierent solutions. Extend your argument to explain the fact that if a system has more than one solution, then it must have innitely many dierent solutions. 2...
