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?
2.5 times
5 times
9 times
18 times

plug in 15 into f(x) to get the bear population. What do you get?
OpenStudy (freemap):
12
830 * 12=9960
OpenStudy (anonymous):
Is the x an exponent in that equation?

sorry yes thereofore
.035
830 * 0.35=290.5

I think you moved the decimal place. Keep it as 0.035
830*0.035 = 29.05
OpenStudy (freemap):
ok
OpenStudy (anonymous):
Then, from the table, in year 15 the cheetah pop. is 266
266/29.05 = 9.2
OpenStudy (freemap):
So that would be C because 9.2 = 9
