5. A marine biologist is testing a new under-water sensor, The sensor is thrown from the ship into the air, goes down under water to a specific depth, and then returns to the surface where it can be collected. The function that models the path is f (@) - 1508 - 1951 + 450 , where i is time measured in seconds. The sensor enters the water at 3 seconds. How long is the sensor underwater? [2A] 5. Given the table of values, find the degree of the polynomial. Show your work. [2K] 52 -2 12 -1 4 10 1 12 2 7. The point (9, 1) is on the transformed function f(() = -(3(1 -1)3 - 4. Use the transformation statement to find the original function's point on the parent function. Justify your answer. [3A]
