Let's consider a scenario where a soccer ball is kicked into the air from a height of 4 feet. In this case, we can use the quadratic function to model the height of the ball over time:
\[ y = -16t^2 + 4 \]
In this function, \( y \) represents the height of the soccer ball in feet, and \( t \) represents the time in seconds since the ball was kicked. The constant value \( 4 \) signifies the initial height from which the ball is kicked, while the coefficient \(-16\) represents the acceleration due to gravity (in feet per second squared), indicating how quickly the ball descends. To find when the ball will hit the ground, we can set \( y = 0 \) and solve the equation for \( t \).
