An underwater camera has been placed in the center of the 25-meter pool at the Grandtown
Aquatic Center to take pictures of swimmers during a swim meet. The camera will go off at
different times depending on the distance of the swimmer to the camera. If the swimmer is
moving at a constant rate of 1.28 meters per second, then you can represent the distance the
swimmer is from the camera after x seconds using the function dix) = 1.28lx-9.77l.
