The rule that describes this translation is (x,y)→(x+3,y-6)
Step-by-step explanation:
In this question, first find the image of the object coordinate under the translation.The object coordinate is at (1,3).
Going 3 units to the right will be (1+3) to get x coordinate for image as 4
Going 6 units down will be (3-6) to get y coordinate for image as -3
The image coordinate will be (4,-3)
The rule is translation (x,y)→(x+3,y-6)

I am assuming that your function is

due to the fact you did not write x-1
the domain is the numbers you can use for x without getting wierd results
wierd results happen when you divide by 0 or take the square root of a negative number
the arean't any division signs so no division by 0
but there is a square root sign
so the part under the square root must be greater than or equal to 0
find where it is equal to 0
0=x+6
minus 6
-6=x
when x is smaller than -6, we get undefined because we get square root of a negative
so the domain (numbers you can use for x) is D={x|x≥-6} or basically x≥-6
