Answer:

The third answer: x+1

Step-by-step explanation:

Remember when writing roots, the signs are backwards. This is because you start with (x-__) and fill in the root.

So for x = -1, it'll be written as (x+1) [aka (x- -1)]

For x = -3, it'll be written as (x+3)

For x = 5, it'll be written as (x-5)

The only answer that is one of these is the the third answer
