The function y = (x- 1)(x-2)(x - 3) is negative on the interval(s) %3D O a) xe (-0, 1) and x e (2, 3) O b) xE (1, 2) and x e (3, 0) c) xe (2, 3) d) xe (1, 2)

2. (a) (5 points) Let f(x) = Vx +1 and g(x) = a² + 2x. Find (f o g)(1) and (go f)(1). 1+x (b) (5 points) Find the inverse of the function f(x) = %3D - x

Let f(x) 1 and g(x) = 4x + 5. x – 4 Then (f o g)(6) (f o g)(x) =

Let f(2) = 7- Va? +1 and g(x) = x- 6. %3D Then (fo g)(2) %3D (f o g)(x) =
