What is the domain of this function?

To find the domain of the function represented by the given sets, we need to identify the unique input values (or x-values). In this case, the values can be found in the first position of each set.

From the sets:

– First set: -5

– Second set: -2

– Third set: -5

– Fourth set: -2

The unique x-values (inputs) are: -5 and -2.

Thus, the domain of the function is the set of unique input values: {-5, -2}.
