The domain and the range depends on the context. For example, the domain and the range can be the whole of the complex field. Or I could define the domain as {-2, 1, 5} and then the range would be {0, 3, -21}. When either one of the range and domain is defined, the other is implied.
The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).
negative infiniti to positive infiniti
In the complex field, the domain and range are both the whole of the complex field.If restricted to real numbers, the domain is x >= 4 and y can be all real numbers >= 0 or all real numbers <= 0 [or some zigzagging pattern of that set].

- ln ((x^2)-4)
4 squared minus 2 squared equals 12
square root of 8
The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
If x squared -10 = 0 then x = the square root of 10
sqrt(4a2) = 21plus or minus (2a) = 21plus or minus (a) = 10.5a = +10.5a = -10.5
Yes and x = 2+square root of 6 or x = 2-square root of 6
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
2
The square root of 28 minus the squared root of 7 =±2.64575131
It is: 9-4 = 5
