How to know if range is all real numbers
Web11 okt. 2016 · 1 I am finding the range of the following function f: R → R f ( x) = ( x + 1) 2 + 1 From the definition, I got that ∀ x ∈ R f ( x) ≥ 1 It is obvious to notice that since x ∈ R, x takes every possible real number. From the definition we can say that ∀ x ∈ R f ( x) ≥ 1 range of f ⊂ [ 1, ∞). Web17 jul. 2007 · Hence the domain is all real x, except x=2 and x=3. In a graph, around these points, the value of y will go to ±infinity. Another example. y = (x)^ (1/2) Here when x<0, the function is undefined (complex) in real range. So the domain of the function is x ≥ 0. For this one - the graph simply does not exist in the negative domain.
