Yes, they are both functions.
50-x^2=0
Move the x^2 to the other side
x^2=50
Now take the square root of both sides
x=+_(50)^1/2 (^1/2 means square root)(+_ is plus or minus. Sorry XD)
Now simplify the square root
X=+_5(2)^1/2
Voila. The answer is C
According to your image which has a diagram where 2 planes are both perpendicularly attached to each other. So base on your diagram I conclude that the answer is C. There are two segments along the planes intersect. I hope i answered your question
