The sum
Using arithmetic progression, we have:

Where:
--- first term
--- last term


So, we have:




The answer is the first option: it has the same domain as the function f(x) = - √(-x).
The domain is the set of x-values for which the function is defined.
The square root function is defined only for zero and positve values.
- x is positive when x negative.
So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
0x+2 =y
So technically x+2=y
