Final answer:
To write the set builder notation for Saturday and Sunday, use x , where 'x' satisfies the condition of being a weekend day and must be either Saturday or Sunday.
Step-by-step explanation:
To write the set builder notation for a set that includes only Saturday and Sunday, we need to specify a property that these two elements share, which is that they are both weekend days. The set builder notation expresses the set in terms of a variable and a condition or property that the elements of the set satisfy. Below is an example of how this could be done.
The set builder notation for the set containing Saturday and Sunday would look like this:
x
Here, 'x' represents the elements of the set, and the condition on the right side of the vertical bar '|' explains the characteristics of the elements in the set. The conditions specify that 'x' must be a day of the weekend, and it must be either Saturday or Sunday.
