The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
y=-x^2 +7 The range is the possible values of y for all acceptable values of x. In this case x can be anything, so at its smallest value of 0, y=7, and at its largest value of infinity, y=negative infinity, so the range is negative infinity to 7.

The domain and range can be the whole of the real numbers, or some subsets of these sets.
Both extend from negative infinity to positive infinity.

Integers are whole numbers that go from negative infinity to positive infinity. As such, they do cover the negative range of the number line.

The domain and range are (0, infinity).Both the domain and the range are all non-negative real numbers.
Both extend from negative infinity to positive infinity.
The range of a function when you consider a graph is how high and how low it goes. A quadratic function is usually an arch that goes up to a high point and then back down like the arch of a kicked ball. Or, it can be the reverse which goes down and then up in a mirror image of a kicked ball. The range is what y values would be needed to show ALL the graph. Example; y=x^2+5x-6 The graph crosses the x axis at -5 and 1 it goes down then back up. The range is from infinity down to -49/4
Yes, but x would be a function of y, not the other (usual) way round. The domain of the function would be y in (-infinity, +infinity) and the range x in [0, +infinity).
Let the function be f(x) = 1/(x-1) The domain is all allowable values for which the function can be defined. Here, except 1, any number would give the function a meaningful value. If x=1, the denominator becomes 0 and the function becomes undefined. Therefore, the domain is all real numbers except 1. The range is all values assumed by the function. Here, the range is negative infinity to plus infinity (that is , all real numbers).
If you mean the arcsin function then the range is the whole of the real numbers - from "minus infinity" to "plus infinity". If you mean the cosecant function, the answer is the whole of the real numbers excluding (-1, 1).
The signed integer range extends only from negative infinity to positive infinity. You have to make up your own names and symbols for whole numbers that are not included in that range.
