SOLUTION: Rationalize the function and give its domain in interval notation:
F(x) = {{{ (2+sqrt(x-3))/(5+sqrt(x-3)) }}}
So far for my work: I first, multiplied by the conjugate; {{{ 5-sq

Yes, multiply the entire expression by , and simplify from that multiplication.
Result of that after simplification should be
Or if multiply again by you could have as
-
The radical forces the restriction and the denominator cannot be allowed 0, so forces the restriction .
