The image contains some mathematical questions that involve functions, compositions, and their inverses. Let's break them down:

1. \( f(x) = 5x - 6 \)

   a) Find \( g(x) \) if \( (f \circ g)(x) = 5x + 9 \).

   b) Find \( g(-2) \) if \( (g \circ f)(x) = 5x - 3 \).

2. \( f(x) = \frac{x + 6}{2x - 5} \) and \( g(x) = 3x + 1 \).

   a) Find \( (g \circ f^{-1})(x) \).

   b) Find \( (g \circ f)^{-1}(x) \).

3. The third question is incomplete, as only "dk" is written.
