1.) How do I find f(40) rounding to two decimals ? 2.) Rewrite using long division to perform (80x-8000) divided by (x-110). Then use the answer to find f(40). 3.) how do the answers from problem 1/2 compare? 4)is f a polynomial?

During the 1980s, the controversial economist Arthur Laffer promoted the idea that tax increases lead to a reduction in government revenue. Called supply-side economics, the theory uses functions such as f ( x ) = 80x - 8000 x - 110 , 30 s x S 100 This function models the government tax revenue, f(x), in tens of billions of dollars, in terms of the tax rate, x The graph of the function is shown. It illustrates tax revenue decreasing quite dramatically as the tax rate increases. At a tax rate of (gasp) 100%, the government takes all of our money and no one has an incentive to work. With no income earned, zero dollars in tax revenue is generated. Use function f and its graph to solve. f(x) = 80.x - 8000 80 x - 110 60 Government Tax Revenue (tens of billions of dollars) 40 At a 100% tax rate, 20 $0 in tax revenue is generated.
