Consider the functions $f(x) = \sqrt[7]{\frac{x}{6}} + 2$, $g(x) = \sqrt[7]{\frac{x - 2}{6}}$, $h(x) = 2 + 6 x^{7}$, $p(x) = \sqrt[7]{\frac{x}{6}} - 2$, $q(x) = -2 + 6 x^{7}$, and $r(x) = \sqrt[7]{\frac{x + 2}{6}}$.
Which of these functions are inverses of each other?

A. $g(x)$ and $h(x)$
B. $h(x)$ and $p(x)$
C. $q(x)$ and $r(x)$
D. $g(x)$ and $q(x)$
E. $h(x)$ and $r(x)$
F. $f(x)$ and $h(x)$
G. $p(x)$ and $q(x)$
H. $f(x)$ and $q(x)$
I. No pairs of these functions are inverses of each other.
