Web9 dec. 2024 · It is possible that this could be written into a sentence to specify the domain of a function, e.g. "The domain of f is all x such that x ∈ R ." However, this sentence is somewhat clunky. Of the options presented, { x ∣ x ∈ R } is the best. It specifies a set (rather than an element of a set) in a completely unambiguous manner. Web5 dec. 2024 · To calculate the domain of a square root function, solve the inequality x ≥ 0 with x replaced by the radicand. Using one of the examples above, you can find the domain of f (x) = 2\sqrt {x + 3} f (x) = 2 x +3 by setting the radicand ( x + 3) equal to x in the inequality. This gives you the inequality of x + 3 ≥ 0 x+ 3 ≥ 0
