Study Notes
Domain Restrictions in Algebra II
- Even index requires non-negative input values for real numbers; therefore, x must be greater than or equal to zero (x ≥ 0).
- When a variable appears in the denominator of a fraction, it cannot equal zero, leading to the restriction x ≠ 0.
- An even index combined with a variable in the denominator of a fraction imposes a stricter condition where x must be positive (x > 0).
- Instances where there are no restrictions on the variable allow for the use of all real numbers in the domain.
