Domain of discrete function
WebMar 24, 2024 · A function from A to B is a rule that assigns to every element of A a unique element in B. We call A the domain, and B the codomain, of the function. If the function is called f, we write f: A → B. Given x ∈ A, its associated element in B is called its image under f.

I don't know … WebMar 15, 2024 · A function is increasing on some interval of its domain if f(a) > f(b) for all a, b in that interval such that a > b. ... Notice that this is a discrete function, and the intervals are ranges of specific points. That is, the function is decreasing if, when we look at the graph, the points are sloping down from left to right. ...
WebIf you have a function f: Z → R, it would be natural to extend it preserving continutity to f ¯: R → R by making it affine on each segment [ n, n + 1]. Then you are able to check if its convex or not. Another way to define a concave function, I think, is to check if g: Z → R, g ( n) = f ( n + 1) − f ( n) is an increasing function. Share Cite Follow WebA function is a rule that assigns each element of a set, called the domain, to exactly one element of a second set, called the codomain. Notation: f: X → Y is our way of saying that the function is called f, the domain is the set X, and the codomain is the set Y.
WebJul 18, 2024 · The domain of a function is all possible values of x that can be used as input to the function, which will result in a real number as the output. The range of a function is the set of all possible output values of a function.
