Unfortunately, we cannot find the domain and range of the relation as it has not been provided in your question. However, let's go over the general procedure of how to find the domain and range of a relation.
The domain and range of a function are sets of numerical values. In simple terms, the domain of a function is the set of "input" or "argument" values for which the function is defined. These are typically the x-values that you would substitute into the function.
The range, on the other hand, is the set of "output" values that come out from the function. These are the y-values that we get after substituting in the domain.
Now let's discuss about interval notation. An interval is written as [a, b] or (a, b). The square brackets [ and ] denote that the endpoints are included in the set, while the parenthesis ( and ) denote that they are not.
Here's an example:
For a function f(x) = x^2
The domain would be all real numbers (-∞, ∞), because x can take any real number and produce a valid y-value output. In interval notation, we express this as (-∞, ∞).
The range of f(x) = x^2 is [0, ∞), because for any real number that you square, you will get an answer of 0 or above, hence the range starts at 0 (included, hence the square bracket) and extends to positive infinity.
Remember, this is just an example. Again, your question doesn't provide a specific relation to determine its domain and range.
