Biologists have proposed a cubic polynomial to model the length L of Alaskan rockfish at age A: L = 0.0155A³ - 0.372A2+ 3.95A + 1.21, where L is measured in inches and A in years. Calculate dL dA A = 17 dL = in/yr dA A = 17 Interpret your answer. O A 17-year old rock fish shrinks at a rate of 4.741 in/yr. O A 17-year old rock fish grows at a rate of 57.559 in/yr. O A 17-year old rock fish grows at a rate of 4.741 in/yr. O A 17-year old rock fish grows at a rate of 62.300 in/yr. O A 17-year old rock fish shrinks at a rate of 62.300 in/yr. (Round your answer to three decimal places.)
