A scientist plans to launch a submarine from a crane on a boat. The submarine's distance from the water can
be modeled by the function y = x - 8x+7, where x is the time in seconds and y is the distance of the
submarine from the water. (Positive y values indicate being above water. Negative y values indicate being
below water) To test the crane, the scientist lowers the submarine to its maximum depth and then raises it
a. What is the maximum depth of the submarine? Explain how you found your answer.
How long does it take for the submarine to hit the water? Explain how you found your answer.
c
How long is the submarine underwater? Explain how you found your answer.
