The independent variable is the year and the dependent variable is the population The domain of the function is the years from the minimum value of 1950 to the maximum value of 2000 The range of the function is the populations from the minimum value of 2 billion to the maximum value of 6 billion Round to the nearest integer as needed) b. Choose the correct description below A. The function shows that there has been a relatively constant world population since 1950 O B. The function shows an initial increase in population, but then a decrease in population closer to 2000 C. () D. The function shows a steady increase in population from 1950 to 2000.

Explanation / Answer

a. all are correct

Independent variable: Year- on x-axis.

Dependent variable: Population - as it is dependent on the value of year and the growth over the given year.

The domain of the function is Year because we find the population based on the given year only. Min and max values: [1950,2000]

Range of the function is Population because the function f(x) = y, values on y axis are outputs i.e Range. Min and max values [2,6]

b. Option C is correct

The population is keep on increasing year on year. it is increasing steadily.

Option D is incorrect because, rate of increase in population (slope of the graph) is not increasing always because in year 1970-1980, the rate of increase is less compated with previous year.
