Formula and explanation
For an even root function y = [n] f(x) (where n is even), its domain requires the expression under the radical to be non - negative. Formula: x ∈ R f(x) ≥ 0 Applicable Conditions: n is even, f(x) is a real - valued expression. Brief Explanation: In the real number system, the radicand of an even root must be greater than or equal to zero.
