You work for a company that is being accused of monopoly behavior, given its large size. Comparisons are made to the industry standard, where each establishment has on average about 16.5 employees. Your company is bigger than that, but you want to provide evidence against the monopoly charges.

You've collected data at different times in your company's history, when you had different amounts of capital.

In 2008, SRATC = 4.5Q² - 120Q + 4,500

In 2013, SRATC = 2.1Q² - 280Q + 12,000

In 2018, SRATC = 2.3Q² - 250Q + 8,000

Plot these three different SRATC curves (have Q go from 0 to 100 in units of 5; make the maximum on the vertical axis be 6,000), and discuss how (and possibly why) your company has changed since 2008 in terms of its size.
