Find the domain of each of the following functions given by

Given:

To find: the domain of function

Explanation: So, the domain of a function consists of all the first elements of all the ordered pairs, i.e., x, so we have to find the values of x to get the required domain

Given,

Now for real value of

x²-1≠0

⇒ (x-1)(x + 1)≠0

⇒ x-1≠0 or x + 1≠0

⇒ x≠1 or x≠-1

Hence the domain of f = R-{-1, 1}
