You would likely benefit far more from learning the definitions of "domain" and "range" than from being given the domain and range in each of these cases.
The domain of a function includes all values of the independent variable for which the function is defined (that is, for which there is a graph). In Case 1, x can have any real value, and so the domain is (-infinity, infinity).
The range of a function includes all values that the dependent value can have (that is, for which there is a graph). In Case 1, y can take on any real value, and so the range is (-infinity, infinity).
Contrast this case to Case 2. Here, y has only ONE value, so the range is simply y=2, or {2}. x can take on any value, so the domain is (-infinity, infinity).
When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.
Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be:
Angle E < Angle F < Angle D
