The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year, and in 2006 the average annual salary was $82,000. Let y represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and y? y = 70(1.17)x
y = 82(1.17)x
y = 70(2.2)x
y = 82(2.2)x

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
