1. Graph the function and identify the domain and range

y=-2x^2

2. Solve the system.

y=x^2+2x-2

y=x+10

3. Solve the equation:

x^2+11x-26=0

4. You throw a ball upward. Its height h, in feet, after t seconds can be modeled by the function

h=-16t^2+30t+6 After how many seconds will it hit the ground?

5. How is the graph of

y=-2x^2+5 different from the graph ofy=-2x^2?
