As it's a square root the underroot value must be greater than or equal to 0
So
let's find out the domain
- √4x+11≥0
- 4x+11≥0
- 4x≥-11
- x≥-11/4
Domain
This is not a function because it does not pass the vertical line test.
Hope this helps!!

The answer to this question is C=6
(-1, -11)
13 is 7 away from 6, and -1 is 5 away from 6. Subtract 7 away from 6, and 5 away from -6.
