Question
In the year 2000, a demographer predicted the estimated population of a city,
which can be modeled by the function f(x) = 5x* – 4x° + 25x + 8,000. Several
years later, a statistician, using data from the U.S. Census Bureau, modeled the
actual population with the function P(x) = 7x* – 6x° + 5x + 8,000. Let x represent
the number of years since 2000. The graphs of the functions are shown.
Complete parts a through c.
a. What is the y-intercept of each function, and what does it represent?
The y-intercept for f(x) = 5x* – 4x° + 25x+ 8,000 is
population of the city in.
The y-intercept for P(x) = 7x* – 6x° + 5x + 8,000 is
which represents the
