Answer 1

Answer:

C

Step-by-step explanation:

If you simplify the equation you get $\sqrt{\frac{x+3}{1-x} }$.  To solve a square root function, you need to set up$\sqrt{\frac{x+3}{1-x} }\geq 0$. You can take the square root of both sides to get $\frac{x+3}{1-x} \geq 0$. Then, we identify the intervals that will satisfy the equation, which is -3 ≤ x < 1.

Sorry if the explanation is kind of confusing, I wasn't sure how to describe it.
