How do you find the domain and range of a function?
General
ScanSolve AI Answer
The domain is all possible x-values (inputs) and the range is all possible y-values (outputs). Common restrictions: denominators ≠ 0, square roots need non-negative radicands, logarithms need positive arguments. Example: f(x) = √(x-3) → Domain: x ≥ 3 (or [3,∞)), Range: y ≥ 0 (or [0,∞)). For f(x) = 1/(x-2), Domain: all reals except x=2, Range: all reals except y=0.
