Problem #2: Suppose that you were to try to find a function of the form y = ax* + bx- + ox that passes through the (x, y) pairs [2 marks] (2, 1), (5, 9), and (7, 5). To obtain the coefficients a, b, and c you would try to solve a system of linear equations whose augmented matrix is which of the following? 16 4 2 16 4 2 16 4 N 16 4 (A) 3125 25 U 9 (B) 3125 25 (C) 625 25 (D) 525 25 2401 343 7 5 2401 343 7 2401 49 5 2401 49 5 16 4 4 2 N 1 16 N (E 625 25 (F) 25 - (H) 625 25 9 2401 49 1 U 49 7 U 2401 49 7 5 Problem #2: Select v Save Problem #3: Use Gauss-Jordan Elimination to solve the following system of equations.
