It should be B. That would make it to where the circle touches the y axis at (6,0). I hope this helps.
Answer:
your answer is c
Step-by-step explanation:
This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85
