Inverse Trigonometric Functions · Review Exercise 83

Use this scenario: The population of a city has risen and fallen over a 20-year interval. Its population may be modeled by the following function: $y = 12, 000 + 8, 000 s in (0.628 x),$ where the domain is the years since 1980 and the range is the population of the city.

What are the amplitude, period, and phase shift for the function?
