 Case 1: No Solution Line: y = x - 1 Parabola: y = 2x2 - 8x + 11 Graphical Solution:
The two don't intersect, so there is no solution. Algebraic Solution: y = x - 1 y = 2x2 - 8x + 11 Use the Comparison method: 2x2 - 8x + 11 = x - 1 and solve: 2x2 - 9x + 12 = 0   Because the descriminant is negative, there is no Real answer. No solution Next let's look at the case where the line is vertical >>> |
