Welcome to Bytelearn!

Let’s check out your problem:

Antoine 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 x seconds after Antoine threw it, is modeled by: \newlineh(x)=−2x2+4x+16 h(x) = -2x^2 + 4x + 16 \newlineHow many seconds after being thrown will the ball hit the ground?
