So, in the set. 5 -1 6 -2 0 The highest number is 6 and the lowest number is - 2, so the range is: 6 - (-2) = 6 + 2 = 8 Think of it as the distance between 6 and - 2 on the number line, like this: ---|---|---|---|---|---|---|---|---|---|---|---|-- ... -3 -2 -1 0 1 2 3 4 5 6 7 8 ...
In mathematics, and more specifically in naive set theory, the range of a function refers to either the codomain or the image of the function, depending upon usage. Modern usage almost always uses range to mean image. The codomain of a function is some arbitrary set. In real analysis, it is the real numbers.
