Question
70x - 7,000
The function f(x) =
40 sxs 100, models the tax revenue, f(x), in tens of billions of dollars, in terms of the tax rate, x. The graph of this function is shown to the right. It illustrates tax revenue decreasing dramatically as the tax rate increases. At a tax rate of 100%, the government takes all our money and no one has an incentive to work. With no income earned, zero
x- 110
dollars in tax revenue is generated. Complete parts (a) through (c) below.
a. Find f(40).
f(40) = (Round to the nearest integer as needed.)
Interpret your result. Choose the correct answer below.
O A. When the tax rate is 40%, S800 billion in tax revenue is generated.
O B. When the tax rate is 87%, $400 billion in tax revenue is generated.
O C. If the tax rate increases 40%, an additional $600 billion in revenue is generated.
O D. If the tax rate increases 87%, an additional $400 billion in revenue is generated.
Identify the solution as a point on the graph. Choose the correct graph below.
