Let A = {x ϵR : –4 ≤ x ≤ x ≤ 4 and x ≠ 0} and f : A → R be defined by Write the range of f.

Given:-

(i)

(ii) f : A → R

(iii)

For

Range ={-1,1}

If f : R → R defined by f(x) = 3x – 4 is invertible then write f^–1(x).

If f : R → R, g : R → R are given by f(x) = (x + 1)² and g(x) = x² + 1, then write the value of fog (–3).

Let be defined by f(x) = sinx. If f is a bijection, write set A.

Let f : R → R⁺ be defined by f(x) = a^x, a > 0 and a ≠ 1. Write f^–1(x).
