In mathematics, domain means: The set of all input values for which a function is defined; for f(x) = 1/x, the domain is all real numbers except 0.
In Turkish: tanım kümesi
How it is used
Usually paired with 'range', the set of possible output values. You state, find or restrict the domain. Values are left out when they make a denominator zero or put a negative number under a square root.
Example sentences
State the domain and range of the function.
The domain of √(x − 3) is x ≥ 3.
Common collocations

Related terms
functionA rule that takes each input from a set and gives exactly one output, for example f(x) = 2x + 1, which doubles a number and adds one.
inverse functionA function that reverses the effect of another function, so that if f(2) = 7, the inverse of f takes 7 back to 2.
denominatorThe number below the line in a fraction, which shows how many equal parts the whole is divided into; in 3/8, the denominator is 8.
setA well-defined collection of distinct objects, called elements, usually written inside curly brackets, such as {2, 4, 6}.
