Q. Amir stands on a balcony and throws a ball to his dog, who is at ground level.The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by:h(x)=−(x−2)2+16What is the height of the ball at the time it is thrown?meters
Identify initial time: Identify the initial time of the throw. The initial time of the throw is when x=0 seconds, since x represents the time in seconds after Amir threw the ball.
Substitute into equation: Substitute the initial time into the height equation.To find the height of the ball at the time it is thrown, we substitute x=0 into the height equation h(x)=−(x−2)2+16.h(0)=−(0−2)2+16
Calculate initial height: Calculate the height at the initial time.h(0)=−(0−2)2+16h(0)=−(−2)2+16h(0)=−4+16h(0)=12 meters
