Growth in length of haddock: In 1933, Riatt found that the length L of haddock in centimeters as a function of the age t in years is given approximately by the formula L = 53 – 42

a. Calculate L(4) and explain what it means.

b. Compare the average yearly rate of growth in length from age 5 to 10 years with the average yearly rate of growth from age 15 to 20 years. Explain in practical terms what this tells you about the way haddock grow.

c. What is the longest haddock you would expect to find anywhere? ➞
