Try solving for y.

(y-1)^2=64-x^2
Two separate functions together: and
and you can consider where y is bounded and what is x allowed to be... fine..
but you could also use graphical knowledge about this circle.

Using graphical knowledge, the center is at (0,1) and the radius is 8 units.

The circle has a range set of 1-8 to 1+8, or y is .

The domain is for the upper semicircle and for the lower semicircle, actually for TWO functions, those listed above when solved for y. The domain is the set of points
