Answer 1

The independent variable, x, represents the number of years working at the company. The dependent variable, C(x), represents the salary. The salary depends on the number of years working at the company because the salary increases by $2,000 for each year of work. A function relating these variables is C(x) = 35,000 + 2,000x, where x is the number of years working at the company and C(x) is the salary. So C(4) = 35,000 + 2,000(4) = $43,000 meaning that if Emily works for 4 years, her salary will be $43,000.
