Question

The length (in centimeters) of a common commercial fish is approximated by the von-Bertalanffy growth function  where a, b, and k are positive constants. Select the graph of f.

Quizplus · Accepted Answer

The von-Bertalanffy growth function describes a sigmoidal curve, starting at 0 and approaching a horizontal asymptote as time (or age in this case) increases. The shape of the graph is determined by the values of a, b, and k, but all options except for A have curves that either do not start at 0 or do not approach a horizontal asymptote. Therefore, A is the best choice.
