Identify the following set as finite or infinite. {x|x is a real number}
The set is infinite because the number of elements in the set is not a whole number.
Determine whether the set is well defined {x|x
The set is not well defined because the membership is a matter of interpretation.
Determine whether the set is well defined. {x|x is a negative integer}
The set is well defined because membership can be clearly determined
