Another example is the function x 7→1/x, in which case all values of x except for x = 0 are allowed. Definition. The domain of a function f consists of all values of x for which the value f(x) is defined. For a function defined by a table, its domain consists of numbers in the first row: . x.
If only the rule y = f(x) is given, then the domain is taken to be the set of all real x for which the function is defined. For example, y = √ x has domain; all real x ≥ 0. This is sometimes referred to as the natural domain of the function. 1.1.4 Range of a function For a function f: X → Y the range of f is the set of y-values such that ...
Domain is all the values of X on the graph. So, you need to look how far to the left and right the graph will go. There can be very large values for X to the right. Range is all the values of Y on the graph. So, you look at how low and how high the graph goes. Hope this helps.
