Scientists studied two animal populations. Function f(x) = 830(0.8)^x models a bear population in a given region x years after the study began. The table models the cougar population in the same region. Use the table of data to interpret a linear function.

Fifteen years after the study began, about how many times greater was the cougar population than the bear population?
