If they create a 90 degree angle then yes.
I think it's A. One way you can identify if they are parallel is if both of the slopes are the same (also both have to have the same signs).
Answer:
Option B is correct.
The domain of the function h(x) is: 
Step-by-step explanation:
Domain states that the complete set of all the possible values of the independent variable where function is defined.
Given the function:

To find the excluded value in the domain of the function.
equate the denominator to 0 and solve for x.
i.e

⇒x = 0 and 
⇒x = 0 and 
or
x = 0 and 
So, the domain of the function h(x) is the set of all real number except x = 0 and 
Therefore, the domain of the function h(x) is:
