From the graphs of f and g in the figure, we find the following. (Assume that each point lies on the gridlines.) (f + g) (8) = (f - g)(8) = (fg) (8) = (2 ) (8) = XAssume that f is a one-to-one function. (a) If f(8) = 1, find f -1(1). (b) If f -(4) = -3, find f(-3). Find f+ g, f g, fg, and fly and their domains. f(x) = X2 + X, g(X) = X2 I! 3 0. rs n + [Q V A X :4 Find the domain of (f + g)(x). (Enter your answer using interval notation.) I :3 o. n 5, I "Q v A >
