The range is a subset of the codomain, meaning that every value in the range is also in the codomain.
The range is a subset of the codomain: The codomain of a function is the set of all possible output values.The range of a function has several important properties that are useful for analyzing the behavior of the function and the properties of a dataset. The domain of this function is all real numbers, and the range is the set of all non-negative real numbers since any non-negative real number can be obtained by squaring a real number. For example, consider the function f(x) = x^2. This means that the range of f is the set of all y values in B that can be obtained by plugging in an x value from A into the function f(x).
