The average annual salary of the employees of a company in the year 2005 was $80,000. it increased by the same factor each year and in 2006, the average annual salary was $88,000. let f(x) represent the average annual salary, in thousand dollars, after x years since 2005. which of the following best represents the relationship between x and f(x)?

The expression of this would be 3.75x+y= 23

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
