determining the largest set D of real numbers
hi guys i got another example here which im not to confident with..

f : D -> R
$
h(x) = \frac{1}{\sqrt{x}-6}+1$

im thinking this would have a slightly different approach because not the whole thing is getting squared.

Since denominator can't be zero x is not equal to 36

Since negative inside square root is not allowed

x (>=) 0

these are the only two conditions
