Use the functions f(x) = x^2 - 1 and g(x) = 2x + 7 to answer parts (a)-(g). (a) Solve f(x) = 0. (d) Solve f(x) > 0. (g) Solve f(x) ? 1. (b) Solve g(x) = 0. (e) Solve g(x) ? 0. (c) Solve f(x) = g(x). (f) Solve f(x) > g(x). (a) The solution to f(x) = 0 is x = -1, 1. (Type an integer or a fraction. Use a comma to separate answers as needed.) (b) The solution to g(x) = 0 is x = (Type an integer or a fraction. Use a comma to separate answers as needed.)
