Use the graph to determine a. the function's domain; b. the function's range; c. the x-intercepts, if any; d. the y-intercept, if any; and e. the missing function values, indicated by question marks, below. f( - 2) =? f(2) =? Use the graph to determine a. the function's domain; b. the function's range; c. the x-intercepts, if any; d. the y-intercept, if any; and e. the missing function value, indicated by the question mark, N below. f(9) = ? Use the graph to determine a. the function's domain; b. the function's range; c. the x-intercepts, if any: d. the y-intercept, if there 3 s one; e. the following function values. ( - 4) f(3) The bar graph to the right shows the wage gap between men and women for Wage Gap Between Men and Women selected years from 1980 through 2010. The function G(x) = - 0.01x~+x +55 models the wage gap, as a percent, x years after 1980. The graph of function G 90- s shown below the actual data. Use this information to complete parts a and b. 609% Wage Gap (percent) a. Find and interpret G(30). 1980 1990 2000 2010 Year O A. G(30) = 76, which represents a wage gap of $76,000 in the year 2010. The Graph of a Function O B. G(30) = 81, which represents a wage gap of 81% in the year 2010. Modeling the Data O C. G(30) = 76, which represents a wage gap of 76% in the year 2010. 90- O D.
