A population of 1500 deer decreases by 1.5% per year. At the end of 10 years, there will be approximately 1290 deer in the population. Which function can be used to determine the number of deer, y, in this population at the end of t years?

y = 1500(1 - 0.015)t
y = 1500(0.015)t
y = 1500(1 + 0.015)t
y = 1500(1.5)t

An antibiotic is introduced into a colony of 12,000 bacteria during a laboratory experiment. The colony is decreasing by 14.9% per minute. Which function can be used to model the number of bacteria in the colony after x minutes?

f(x) = 12000(1 + 14.9)x
f(x) = 12000(1 - 14.9)x
f(x) = 12000(1 + 0.149)x
f(x) = 12000(1 - 0.149)x
