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

Given:-

(i)f : R → R⁺

(ii)f(x) = a^x, a > 0 and a ≠ 1

Let

f(y)=x

a^y=x

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

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

Let f : R – {–1} → R – {1} be given by Write f^–1(x).

Let be a function defined as

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