Evaluate the function for f(x) = x + 3 and g(x) = x2 – 2. (f + g)(-1) (f + g)(-1) = Need Help? Read It Watch It 8. [-/1 Points] DETAILS Evaluate the function for f(x) = x + 3 and g(x) = x2 – 2. (f - g)(5) (f - g)(5) - Find the following. x2 f(x) = x2 - 16, g(x) = x²+1 (a) (f + g)(x) = (b) (F - g)(x) = (c) (fg)(x) = (d) (f/g)(x) = What is the domain of f/g? (Enter your answer using interval notation.) Find the following. f(x) = 2x + 1, g(x) = x2 - 49 (a) (f + g)(x) = (b) (f- g)(x) (c) (fg)(x) (d) (f/g)(x) What is the domain of f/g?
