find G(F(x))

ganeshie8 (ganeshie8):

G(F(x)) = G(\(\sqrt{x-6}\)) = \(\large \sqrt{\frac{1}{\sqrt{x-3}-3}}\)

ganeshie8 (ganeshie8):

you need to find the domain of that function

OpenStudy (anonymous):

do we need to findx?

ganeshie8 (ganeshie8):

since you have square root, the thing inside must be >=0 also since the botom cannot equal 0, we can have this :- \(\sqrt{x-3} - 3 > 0\)

ganeshie8 (ganeshie8):

solve x

ganeshie8 (ganeshie8):

**thats sqrt(x-6) actually \(\sqrt{x-6} - 3 > 0\) \(\sqrt{x-6} > 3\)

ganeshie8 (ganeshie8):

an u solve x ? :)

OpenStudy (anonymous):

i got d

ganeshie8 (ganeshie8):

yes domain is, x > 15
