does posting a link to openstudy.com count as showing all your work? OpenStudy (anonymous):

the domain does not include places where the square root is negative, and it also skips points where the denominator evaluates to 0. otherwise all the x-values are fair game. OpenStudy (anonymous):

$\sqrt{(-6x-9)}$ means -6x-9 cannot be negative $\ge 0$ add 9 to both sides, and divide by -6 x $\le$ -3/2 The whole denominator cannot = 0 $\sqrt{(-6x-9)} +x$ = 0 subtract x on both sides $\sqrt{(-6x-9)} =-x square both sides -6x-9 = x^2 Get equation = 0 x^2 + 6x + 9 = 0 Factor and solve (x + 3)(x + 3) = 0 x+3 = 0 x = -3 Therefore x is any real number except -3. (-\[\infty$, -3) $\cup$ (-3, $\infty$ )
