9. Example 2
A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression 45∙ 1.5 𝑑 , where d is the number of decades after the population was measured. Evaluate the expression for d= -2, d= 0, and d = 1.

What does each value of the expression represent in the situation of the finches? (look at the values and what d represents)
