Answer:
Step-by-step explanation:
It's about +- 2.2. It equals 2.236067977 but can be rounded to 2.2. When you square root, the answer could be positive or negative.
For ever input, there is one ouput
it means we can't repeat the same x with a different y
but repeats of y's are allowed
pick any numbers that haven't been used as an input
-5 isn't taken
0 is taken
11 is taken
-1 is taken
2 is not taken
17 is taken
so -5 and -1 or A and D are the answers
