A certain city's population is 120,000 and decreases 1.4% per year for 15 years. Is this exponential growth or decay? Growth
What is the rate of growth or decay?
What was the initial amount? 120000
What is the function?
What is the population after 10 years? Round to the nearest whole number.

Step-by-step explanation:

The exponential function for growth/decay is given as:

In this problem:

The city's initial population is 120,000 and it decreases by 1.4% per year.

Therefore, the function is:

When t=10 years

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
