Solve each application of operations and composition of functions.

U.S. Emissions A common air pollutant responsible for acid rain is sulfur dioxide (SO₂). Emissions of SO₂ during year x are computed by ƒ(x) in the table. Emissions of carbon monoxide (CO) are computed by g(x). Amounts are given in millions of tons.

(a) Evaluate (ƒ + g)(2010).

(b) Interpret (ƒ + g)(x).

(c) Make a table for (ƒ + g)(x).
