Use your graphing calculator to help you determine the number and type of solutions to the Quadratic

Equation 2x² - 10 - 8x

1. Begin by putting the equation into standard form.

2. Graph the function on your calculator [Hint: Use the following window on your graphing

calculator: Xmin = -6, Xmax = 10, Ymin = -23, Ymax = 5]

3. IF your solutions are real number solutions, use the graphing INTERSECT method to find them.

4. Draw the parabola neatly below by plotting the highest (or lowest) point and one other point.

5. Place a point on the graph at each of the Horizontal Intercepts, if any

6. Below the graph,

identify the number of Real Solutions and identify those solutions

Graph the function and plot the Horizontal Intercepts:

-13

-25

-16

-174

-18

-19

-20

-21

Identify the number of Real Solutions (0, 1 or 2):

Identify the Real Solutions rounded to two decimal places: x

[Hint: If two solutions exist, enter the answer as a, b. If only one solution exists, enter a. If none exist,

enter DNE.
