Question 1063759
.
I read your expression as 


sqrt(x + 1) + (1 - x)/sqrt(x)


If your expression is different, then it is your fault (because your formula formally is NOT correct).


In this case, the following conditions must be satisfied:


<pre>
x + 1 >= 0,

x >= 0      and

x =/= 0.

In the interval form, x must belong to the set ({{{0}}},{{{infinity}}} ).
