In 1970 the population of the United States was 203 million. Ten years later, in 1980, the population of the United States was 226 million.

Write a function for the exponential growth of population in the U. S using:

-t(0)=203

-t(0)=226

The exponential function for the US population is:

Step-by-step explanation:

Let be supposed that US population can be modelled by means of the following exponential function:

Where:

- Time, measured in years. Where t = 0 for 1970.

- Initial population, in millions inhabitants.

- Exponential rate constant, in years.

- Population, in millions inhabitants.

Each constant is found hereafter:

A

B

The exponential function for the US population is:

answer: i think it is (1,-2)

all it means is function 3
