Question description

1. Let f(x) = √(x - 4) + 3.

a) Find the inverse of f.

b) Find the range of f -1.
1. Let h(x) = (x - 1) / (-x + 3).

a) Find the inverse of h.

b) Find the range of h.
1. Let f(x) = (x - 1)/(x + 5) and g(x) = 1/(x + 3).

a) Find the composite function (f o g)(x).

b) Find the domain of f o g.
1. Function f is a function with inverse f -1. Function h is defined by h(x) = f(x) + k where k is a constant. Express the inverse function of h in terms of f -1 and k.
1. Function f is a function with inverse f -1. Function h is defined by h(x) = A*f(x - h) + k where A, k and h are constants. Express the inverse function of h in terms of f -1, A, k and h.
