Question

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 300 •3m​, where m is the number of months after the number of visitors was measured. Evaluate the expression for m=minus−1. What does the value of the expression represent in the​ situation?

Answer 1

we have that

the expression is (300)*(3^m)

for m=-1
​(300)*(3^-1)---------> (300)*(1/3)=100
The value of expression at m=-1 is 100, so there were 100 visitors 1 months before the number of visitors was measured
