The function G(x) = -0.01x +x+66 models the
wage gap, as a percent, x years after 1980 in Country A.
The graph of function G is shown underneath the actual
data.
a. Find and interpret G(30). Identify this information as a
point on the graph of the function.
G(30) = 87; in the year 2010, women's earnings were
87% of men's in country A
(Type whole numbers.)
Using the value of G(30), a point on the graph of the
function is (30,87)
(Type an ordered pair.)
b. Does G(30) overestimate or underestimate the actual
data shown by the bar graph? By how much? Select the
correct choice below and fill in the answer box within your
choice.
