... (fg)(x), and  f g  (x), and find their domains. 39. f(x)=ax + b and g(x) = cx + d 40. f(x)=3x + 2and g(x) = 5x − 1 41. f(x)=2x + 3and g(x) =x 2 −1 42. f(x)= 3 x+1 and g(x) = 2x x−5 43. f(x)= √ x and ... There are many ways of decomposing functions. For instance, suppose h(x) = x 2 + 1 x 2 + 2 and we want to find f and g such that f(g(x))=h(x). Determine which of the f...
