Choices A and B have typos in them, so its not clear what you're trying to say for those parts. However, the domain of 
is 
meaning that x can be 0 or larger. In other words, we can't have x be negative. Similarly, y is the same story because has the inverse 
, but only when , so therefore 
as well. In short you can say both x and y are nonnegative.
To summarize so far, the domain is and the range is
Since x = 0 and y = 0 are the smallest x and y values possible, this means (x,y) = (0,0) is the left-most point or where the graph starts. This is the origin. Choice C is a true statement.
Choice D on the other hand is <u>not</u> a true statement. Graph out and you'll see that a straight line does not form, but instead a nonlinear curve that grows forever. That growth gradually diminishes as x gets larger. Algebraically you can pick three points from the function and show that the slopes are different. Say the three points are P, Q and R. If you can show that slope of PQ does not equal slope of QR, then the function is not linear.
Supplementary angles are two angles whose sum equal to 180 degrees. Vertical lines are the opposite angles in the intersecting lines. Thus, each of your angles must be 90 degrees. Just simply draw two straight and intersecting lines.
The X=1 is Y= 5
The x=0 is Y= 8
The x=3 is Y= -1

@jazzybthebest
Step-by-step explanation:
I cannot see the entire problem, but based on what I can see, vertical angles are involved. Just know that vertical angles are always equal. An example would be that 1 and 3 are vertical.
Looking at the problem, the sum of angle 1 and angle 3 is 314. Since angle 1 and angle 3 are equal, angle 1 and angle 3 are both equal to 157. If the question is asking you to solve for angle 4 or 2, then you would use supplementary angles. 180-157 is 23, so the measure or angles 2 and 4 is 23. If the question if something other than what I mentioned, let me know and I will answer that, but I hope what I have helped!
