-sqrt%284%29=-2 but it also equals -sqrt%284%29=-%28-2%29=2 since %28-2%29%28-2%29=4
For x=-2
Real - Yes
Integer - Yes, whole numbers plus negatives of whole numbers
Rational - Yes, it's the ratio of two integers (2 and -1 as an example).
Irrational - No, it's rational, can't be both.
Whole - No, whole numbers are non-negative.
