{1, 2, 5}

Step-by-step explanation:

$\{(1,\ 7),\ (2,\ -4),\ (5,\ 6),\ (2,\ 8)\}\\\\\text{Domain of given relation:}\ \{1,\ 2,\ 5\}\\\text{Range of given relation:}\ \{-4,\ 6,\ 7,\ 8\}\\\\\text{The inverse}\ R^{-1},\text{ of a relation}\ R\ \text{ is the set of ordered pairs obtained}\\\text{by reversing those of}\ R^{-1}=\{(x,\ y):\ (y,\ x)\in R\} \\\\\text{Example:}\\\text{If}\ (x,\ y)\in R,\ \text{then}\ (y,\ x)\in R^{-1}\to (1,\ 3)\in R\to (3,\ 1)\in R^{-1}.\\\\\text{Therefore. The range of the inverse relation is}\ \{1,\ 2,\ 5\}$
