The expression is not defined at x= -2 & for all values of x less than -2 .
<u>Step-by-step explanation:</u>
We have , a given expression as : Basically we need to find domain for this function and see for which values of x the above function is undefined . Domain of a function is the set of values of x for which the function is defined . We have a rational expression,
it's a fractional function which means denominator can be 0 . Denominator =
⇒
⇒
⇒
So , . Also , Denominator is a square root expression so it can't be negative inside root ∴
⇒
i.e. x must be greater than -2.
Therefore, the expression is not defined at x= -2 & for all values of x less than -2 .
