WebApr 18, 2024 · 2 It's widely known, that f = Θ ( g) we understand as "one direction" equality i.e. f ∈ Θ ( g). But when we write something like Θ ( f) = Θ ( g), then situation becomes slightly different: now it is equality between sets, so need proof in "two directions". WebMay 12, 2010 · Take f (n) = 2n and g (n) = n. Then f (n) = Θ (g (n)) because 2n = Θ (n). However, 2 f (n) = 2 2n = 4 n and 2 g (n) = 2 n, but 4 n ≠ Θ (2 n ).
