    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.
