A common air pollutant responsible for acid rain is sulfur dioxide (SO2) . Emissions of (SO2 ) from burning coal during year x are computed by f(x) in the table. Emissions of (SO2 ) from burning oil are computed by g(x). Amounts are given in millions of tons. X 1860 1900 1940 1970 2000 f(x ) 2.4 12.6 24.2 32.2 54.0 g(x) 0 0.1 2.5 17.8 25.0 Answer questions (a) through (c). . . . . . (b) Interpret (1 + g)(x). Choose the correct answer below. O A. (f+ g)(x) computes the quotient of (SO2 ) emissions from burning coal and oil during year x. O B. (f+ g)(x) computes the product of (SO2 ) emissions from burning coal and oil during year x. O C. (f+ g)(x) computes the difference between (502 ) emissions from burning coal and oil during year x. D. (f+ g)(x) computes the total (SO2) emissions from burning coal and oil during year x. (c) Make a table for (f + g)(x). X 1860 1900 1940 1970 2000 (f + g)(x) (Simplify your answer.)
