For each pair of functions, find (fog)(x) and (go f)(x) . Determine the domain of (fog)(x) and the domain of (gof)(x). Show your work. 1. f(x) = 6x +5 and g(x) =2x -4
2. f(x) =4x2-16 and g(x) = Vx+7
3. f (x) = 5 and g(x) = 4x+4
x -4
4. f(x) = 5x +2 and g(x) = x2+1
5. f(x) =2x2 -4x+21 and g(x) = x+3
