Use functions f(x) =x2- 16 and g(x) = - x2 + 16 to answer the questions below. (a) Solve f(x) = 0. (d) Solve f(x) > 0. (g) Solve f(x) 2 1. (b) Solve g(x) = 0. (e) Solve g(x) SO. (c) Solve f(x) = g(x). (f) Solve f(x) > g(x). (a) The solution set is { }. (Type an integer or a fraction. Use a comma to separate answers as needed.) (b) The solution set is {} (Type an integer or a fraction. Use a comma to separate answers as needed.) (c) The solution set is {} (Type an integer or a fraction. Use a comma to separate answers as needed.) (d) Solve f(x) > 0. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The solution set is (Type your answer in interval notation. Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) O B.
