... use systems and matrices to solve the problem. You may wish to perform the first substitution as an example for students. Substituting the first point (–1, 5) into the quadratic equation y = ax2 + bx + c yields 5 = a(–1)2 + b(–1) + c, which simplifies to a – b + c = 5. The other equations follow, an ...
