huh? You have the formula. Just plug in the values for x.
For example,
f(5) = 6500 * 0.9^5 - 40 = 3798
I have no idea which "steps" you need to show. Just evaluate the expression.
Dr. Horton is studying an endangered fox whose population is declining. The population decrease is represented by the function f(x) = 6500(1 - 0.10)^x - 40. She is using this equation to study the population decline from year to year, with x representing each year.
a) Calculate how many foxes there were in year 3 and in year 8. You must show all your work and explain each step.
(please someone help me with this!)

Dr. Suzuki is studying an endangered fox whose population is declining by 20% every year. If there are currently 3,300 foxes, how many will remain in 4 years?
