Question

The function f (x) = 125,000 (1.028)x models the change in population of Pool City, where x represents the number of years since 2010. Which statement is NOT true?

A.) The domain of the function includes all real values of x .

B.) The point (1, 128500) represents the population of Pool City in 2011.

C.) The population of Pool City in 2010 is 125,000.

D.) The function has an asymptote at y = 125,000 .

Answer 1

The statement that is not true is D. The function f(x) = 125,000 (1.028)x does not have an asymptote at y = 125,000. It is an exponential growth function and as such does not have any asymptotes.
