Please help me answer this word problem!!
Use function notation to rewrite all of the following phrases below.
A ball is thrown straight up with a certain speed, then its height above the ground (measured in meters)
after t seconds is given by the following equation:
h(t)=-4.9t^2+25t
1. the height of the ball t seconds after being thrown
2. the height of the ball between 1 and 2 seconds
3. the height of the ball between 1.5 and 2.5 seconds
4. the change per second in the height of the ball between a and b seconds
~~~~~~~~~~~~~~~~~~~~
ANSWERS
1. the height of the ball t seconds after being thrown: h(t).
2. the height of the ball between 1 and 2 seconds: h(1) <= h <= h(2).
3. the height of the ball between 1.5 and 2.5 seconds: h(1.5) <= h <= h(2.5).
4. the change per second in the height of the ball between a and b seconds: .
