Question

A ={x: x E z, x is a solution of x (4) -16=0} then A =?

Answer 1

Answer:

2 = + Ny; c

Step-by-step explanation:

Thus, f(x) is invertible Let g(x) be the inverse of f, so f(g (x)) = x V x e [−1, 1] => 4(g(x))” – 3 g(x) = x Let ... oo) → [2, oo) is given by, f(x) = x ++, then JC f'(x) equals x + Nx” — 4 JC (a) –, (b) To x – Jy” — 4 2 (c) 2 (d) 1–Vx*-4 1 2 Solution: (a) Let y = x +– => y = * +1 JC JC ... (a) Vx-4–2, x > 4 (b) 1 Jo Z: (x+4) (c) N.Y. – 4, x > 4 (d) Nx +4–2, x > –4 Solution: (d) Given h(x) = f'(x) But y = f(x) = (x + 2) = x + 2 = + Ny; c
