To find the time it takes for the ball to reach the ground, we set f(x) equal to 0 and solve for x. The x values are your zeros. I see that you already found your zeros, and they are correct after checking Good work. Since time can never be negative, we accept the positive zero.

Therefore, it takes the ball approximately 3.42 seconds to reach the ground.
