Web11 Feb 2024 · Best answer Given function f: R+ → [−5, ∞) given by f (x) = 9x2 + 6x – 5 Let us show that f is invertible. Injectivity of f: Let x and y be any two elements of domain (R+), Such that f (x) = f (y) ⇒ 9x2 + 6x – 5 = 9y2 + 6y − 5 ⇒ 9x2 + 6x = 9y2 + 6y ⇒ x = y (As, x, y ∈ R+) Therefore, f is one-one. Surjectivity of f: Let y is in the co domain (Q) Web14 Apr 2024 · In order to study rapidly rotating NS in f(R, T) gravity, we start by briefly discussing the main aspects of this modified theory of gravity.. In 2011, Harko et al. [] proposed the theory of gravity f(R, T), where the gravitational Lagrangian is an arbitrary function of the Ricci scalar R and of the trace of the energy–momentum tensor T.The …
