I just need to know if i got this question right. thanks!
Find a function whose graph is the given curve:
The bottom half of the circle x²+y²=9
I got the answer y=± ?(9- x²)
-3?x?3
Though, since it's the bottom half of the circle, would it be y=-?(9- x²) [negative]
how would i simplify that further?
