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.
