W(t) = 1.5 ln ((t/4)+1) where t ≥ 0 and W(t) is the mean weight of a lobster in kg after t months.
a) draw this function so as to depict the mean weight of a lobster over 2 years of its growth
b) Graphically determine the time taken, in months, for the mean weight of a lobster to reach 2.56kg. Check the answer using an algebraic approach
