Instructions: Find the line of symmetry of each quadratic function.
Remember, the line of symmetry for a quadratic function, y = ax2 + bx + c is
x = -b/2a.
How to find the line of symmetry.
1. y = 100x2 + 10x + 5
2. y = -100x2 + 10x + 5
3. y = 12x2 -2x + 144
4. y = x2 + 5x - 1
5. y = -2x2 -16x + 16
6. y = 49x2 + 84x + 36
7. y = 121x2 -198x -81
8. y = 25x2 + 30x + 9
