Codomain vs. Range: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Codomain is the set of all possible outputs of a function, while Range is the actual set of outputs generated by the function.
Key Differences
Codomain refers to the entire set of potential outputs a function could possibly produce, regardless of whether every element is actually an output. Range, in contrast, is the subset of the codomain that consists of all elements that are actually outputs of the function.

In mathematical functions, the Codomain is predefined and includes all values that could theoretically be returned, encompassing values that the function may never actually produce. The Range, however, is determined by the specific inputs used and includes only the values that the function actually returns.

Codomain is a concept that helps define the scope of a function and is an essential part of a function's definition. Range is a result of the function's operation, representing the actual outcomes obtained when the function is applied to its domain.

When visualizing functions, the Codomain can be thought of as the entire target space, while the Range represents the specific area within that space that the function actually maps to.

Understanding the difference between Codomain and Range is crucial in advanced mathematics, especially in fields like calculus and linear algebra, where the distinction impacts the understanding of function behavior and properties.
