What is the coordinate of one x-intercept of the expression (x + 6)(x - 6)?
What is the coordinate of the other x-intercept of the expression (x + 6)(x - 6)?
Which object was launched from a higher point?
Which object reached a higher point?
Which object was launched with the higher upward velocity?
Which object landed last?
What is the coordinate for one zero of the function h(t) = (1 - t)(8 + 16t)?
What is the coordinate for the other zero of the function h(t) = (1 - t)(8 + 16t)?
Which zero is meaningful to the situation?
From what height was the ball thrown?
About when does the ball reach its highest point?
How high does the ball go?
The function f(t) = 6 + 30t - 16t2 models a football's height. Match each part of the function to what it means in this situation. (Note: one of the items on the right will not be used.)
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
+ 30t | arrow_right_alt | Initial Height |
- 16t2 | arrow_right_alt | Initial Speed |
| arrow_right_alt | Effect of Gravity | |
6 | arrow_right_alt | Time in the Air |
The function h(t) = (1 + 2t)(18 - 8t) models an arrow shot into the air. When does the arrow hit the ground?
From what height is the arrow shot?
Which TWO values in the equations should you compare to determine which object was launched from a greater height?
Which object was launched from a greater height?
Which TWO values in the equations should you compare to determine which object was launched with a greater upward velocity?
Which object was launched with a greater upward velocity?
What is the coordinate of the y-intercept of the expression (x + 6)(x - 6)?
