6. The graph will form a parabola. Each graph will have either a maximum or minimum point. There is a line of symmetry which will divide the graph into two halves.

7. x = 3

8. x = 2

11. When a quadratic function is in standard form The equation of the line of symmetry is y = ax 2 + bx + c,

12. For example… Find the line of symmetry of y = 3x 2 – 18x + 7 Thus, the line of symmetry is x = 3. Using the formula…

15. A companys weekly profit, in riyals, is modeled by the function Where u is the number of units sold each week. Find a.The maximum weekly profit b.The loss for a weeks holiday period, where no units are sold c.The number of units sold each week at break-even point for the company
