{"id":20365,"count":1,"description":"In mathematics, the range of a function refers to either the codomain or the image of the function, depending upon usage. This ambiguity is illustrated by the function f that maps real numbers to real numbers with f(x) = x. Some books say that range of this function is its codomain, the set of all real numbers, reflecting that the function is real-valued. These books call the actual output of the function the image. This is the current usage for range in computer science. Other books say that the range is the function's image, the set of non-negative real numbers, reflecting that a number can be the output of this function if and only if it is a non-negative real number. In this case, the larger set containing the range is called the codomain. This usage is more common in modern mathematics.\nBecause of this ambiguity, it is a good idea to specify whether it is the image or the codomain being discussed.\nLet f be a function on the real numbers defined by f(x) = 2x. This function takes...","link":"https:\/\/www.skateboarding-lessons.com\/go\/tag\/range\/","name":"Range","slug":"range","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags\/20365","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/posts?tags=20365"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
