The function f(x) =
-, 30≤x≤ 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 dollars in tax revenue is generated. Complete
parts (a) through (c) below.
a. Find f(30).
f(30) = (Round to the nearest integer as needed.)
