Jun 25, · Answer Stepbystep explanation Hi, the function is defined for all reals so the domain is for x real x >= 0 so f(x) >= 4 so the range isFind the Domain and Range f(x)=5 The domain of the expression is all real numbers except where the expression is undefined In this case, there is no real number that makes the expression undefined Interval Notation SetBuilder NotationSep 23, 16 · We have, f x = x 5 x 5 Clearly f x is defined for all x ∈ R except at x = 5 So, domain of f = R5 Now, f x = x 5 x 5 ⇒ f x = x 5 x 5 = 1, when x > 5 and f x = x 5 x 5 = 1, when x < 5 So, range of f = 1, 1
