Question

The pop. of a city is 75000. It decreases 1.5% annually. Complete the exponential function that models the population after x years.

f(x)=75,000 (_____)^x

Answer 1

formula is f(x) - ab^x. so we would need to get b. we would have to change the percentage to a decimal. so shift it 2 times to the right. which is 0.015 = b. hope this helps :D
