Domain: $x \in {- 1, - 5, - 4, 10, 5}$ $x in {-1, -5, -4, 10, 5}$
Range: $y \in {- 9, - 10, 1, - 6, - 2}$ $y in {-9, -10, 1, -6, -2}$

Explanation:

Assuming the given set represents values of $(x, y)$ $(x,y)$ where $x$ $x$ is being mapped into $y$ $y$ (that is $y$ $y$ is a function of $x$ $x$ ).

If $y$ $y$ is a function of $x$ $x$

$XXXX$ $color(white)("XXXX")$ The domain is the set of all valid values for $x$ $x$ .

$XXXX$ $color(white)("XXXX")$ The range is the set of all valid values for $y$ $y$
