Step-by-step explanation:
Question
A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression
,
where d is the number of decades after the population was measured. Evaluate the expression for d = −2
Given :
The number of finches is modeled by the expression :
⇒ 
where 
is the number of decades after the population was measured.
To evaluate the expression for d=-2
Solution:
In order to evaluate the given expression to find the number of finches at , we will plugin 
for in the expression and simplify it.
Plugging in in the expression:
⇒ 
Using negative exponent property. [
⇒ 
⇒ 
⇒ 
(Answer)
Thus, the number of fringes at is given as 20.
This means the number of fringes two decades ago was 20.
