The quadratic function models the depth, in meters, below the surface of the water of a Weddell seal minutes after the seal entered the water during a dive. The function estimates that the seal reached its maximum depth of meters minutes after it entered the water and then reached the surface of the water minutes after it entered the water. Based on the function, what was the estimated depth, to the nearest meter, of the seal minutes after it entered the water?
