Question

Please Help Me Please !Its A Math question ... The path of a ball being thrown off a building can be modeled by the equation y= -16t^2+64t+80

1.)How long does it take to get to its maximum height?


2.)What is its maximum height?


3.) How long does it take to hit the ground?


4.)What is an appropriate domain and range for this function?


5.)What does the 80 in the equation represent?

Answer 1

1. it takes the ball 2 seconds

2. 144

3. 5 seconds

4. Domain is all real numbers
