All real numbers except zero.
1 over 2 plus 1 over 2= 2 over 2= 1 whole
1/8 plus 1/4 plus 1/2 = 7/8 or 0.875
The restricted value in the domain is x=-2 because if x were equal to -2, the denominator would be 0 and the expression would become undefined.
4 over 8 is the same as 1 over 2, so 1 over 2 plus 1 over 2 (.5+.5 OR 1/2 +1/2) is 1. The answer is 1.
The answer depends on the domain. If the domain is the whole of the real numbers, the range in y ≥ 1. However, you can choose to have the domain as [1, 2] in which case the range will be [2, 5]. If you choose another domain you will get another range.

((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
The domain of the function f (x) = square root of (x - 2) plus 4 is Domain [2, ∞)
For this question, the domain can be anything, as long as the denominator is not 0. If your question was (3x+1)/(x2-2x), the domain is all real numbers except for 0, 2. If your question was [(3x+1)/x2] - 2x, then x is not equal to zero.
