Question

The number of species of a given taxonomic group within a given habitat (often an island) is a function of the area of the habitat. For islands in the West Indies, the formula below approximates the number S of species of amphibians and reptiles on an island in terms of the island area A in square miles.

S(A) = 3 A0.3

This is an example of a species-area relation.

(a) Make a table giving the value of S for islands ranging in area from 4,000 to 28,000 square miles. (Round your answers to two decimal places.)
A
(square miles)
S(A)
4,000
8,000
12,000
16,000
20,000
24,000
28,000

(b) Explain in practical terms what S(24,000) means.

S(24,000) =

(c) Use functional notation to express the number of species on an island whose area is 8,200 square miles.
S(   )

(d) Would you expect a graph of S to be concave up or concave down?
