Short Answer: False
The domain is the x value. It is the power in the equation. You can have almost any value for x depending on what you've been told about infinity. My definition for the domain (for this question) is
- ∞ ≤ x ≤ ∞ for all real values. The graph is almost the same one as the last one I sent you, but it is slightly different.
Answer << False
PS How do you get such clear pictures? It's a joy to read.

Answer: (c) x = -4
Answers:
x = 100
y = 25
==============================================================
Explanation:
Angle y and the 25 degree angle are corresponding angle. Because the lines are parallel, this means that y = 25
Check out the attached image. Using a red pen, I extended one of the lines to form a triangle. From the alternate interior angle theorem, we know that one of the angles of the triangle is 75 degrees (alternate interior angles are congruent). Again this stems from the fact that the lines are parallel.
I've also introduced the variable z to help find x. The angles x and z add up to 180 degrees since they form a straight line. So we need to find z before we can find x.
The triangle's angles 25, 75, z add up to 180. Let's solve for z
25+75+z = 180
100+z = 180
z = 180-100
z = 80
Use this to find x
x+z = 180
x+80 = 180
x = 180-80
x = 100
