Suppose the population of a town is 2,700 and is growing 4% each year. a. write an equation to model the population growth. b. predict the population after 12 years. y = 2,700 • 4x; about 45,298,483,200 people y = 4 • 2,700x ; about 129,600 people y = 2,700 • 1.04x ; about 4,323 people y = 2,700 • 4x ; about 4,323 people

Equation to model the population growth is and  the population after 12 years is  4323 (Approx) .

Step-by-step explanation:

The exponential increase function is given by

Where a is the initial value, r is the rate of interest in the decimal form and x is the time in years .

As given

Suppose the population of a town is 2,700 and is growing 4% each year.

a = 2700

4% is written in the decimal form .

= 0.04

r = 0.04

Thus the equation becomes for population growth.

As given

x = 12 years

Put in the formula

y = 4323 (Approx)

Therefore the population after 12 years is  4323 (Approx) .

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
