What Val are restricted from the domain of

Given:

The given expression is

We need to determine the values for which the domain is restricted.

Restricted values:

Let us determine the values restricted from the domain.

To determine the restricted values from the domain, let us set the denominator the function not equal to zero.

Thus, we have;

Taking square root on both sides, we get;

Thus, the restricted value from the domain is

Hence, Option A is the correct answer.

the answer is a
