answer with a bit of working out pls

5. Find the functions (a) fog, (b) gof, (c) fo f, and (d) go g and their domains. a f(x) = x2 - 1, g(x) = 2x+ 1 b f (x ) = x - 2, g(x) =x2+ 3x +46. 23-24 How would you "remove the discontinuity" of f? In other words, how would you define f(2) in order to make f continuous at 2? x2 - x - 2 f(x) = x3 - 8 x - 2 f (x) = x2 - 4 a) b)
