Practice Making Connections on the Quadratic Web using this **worksheet**:
 * Monday 12/12/2011: Independent Practice #85-90 page 355 QUIZ TOMORROW!!!**
 * Friday 12/09/2011: Turning Graphs into Quadratic Equations:** Use the **zero product property** in reverse to create an equation when you know the x-intercepts.

Example: The x-intercepts are (2,0) and (-4, 0). This means that x = 2 and x = - 4 are zeros of the equation. The **factors** are (x -2) and (x + 4) The **equation** is y = (x - 2) (x + 4)
 * Thursday 12/08/2011: Independent Practice page 352 #75-81 due Monday**
 * Wednesday 12/07/2011: Turning Tables into Quadratic Equations.** Use the **zero product property** in reverse to create an equation when you know the x-intercepts.
 * In-Class Assignment:** Page 353 #8-72

To find the **y-intercept:** Look for the **constant** in the equation. **Example: y = x 2 + 8x - 7** To find the **x-intercepts: Factor** the quadratic. Set the equation equal to zero. Solve both parts of the product for x. **Example: y = (x - 7)(x - 1) = 0**

 * Monday 12/05/2011: Quadratic Equations into Graphs.** If you can find the y-intercept and the two x-intercepts, you can sketch a graph of the parabola.
 * -7 is the y-intercept (-7, 0)**
 * x =7 and x = 1**
