Best ResponseYou've already chosen the best response.0f(g(x)) = (3/x) +2 g(f(x)) = 3/(x+2)

Best ResponseYou've already chosen the best response.0(3+2x)/x = 3/(x+2) (3+2x)(x+2) = 3x 3x +6 +2x^2 +4 = 3x 2x^2 +10 = 0 2(x^2 +5) = 0 x^2 + 5 = 0 x^2 = 5 aint possible no real solutions....

Best ResponseYou've already chosen the best response.0should been: 3x +6 +2x^2 +4x = 3x forgot the "x" on the 4 2x^2 +4x +6 = 0 x^2 +2x +3 = 0 still aint got no "real" values....
