Visualizing Domain and Range with Circles
READ the instructions on the right and INTERACT with the GeoGebra applet below.
Transform the circle (x-h)2 + (y-k)2 = r2
with center at (h,k) and radius r to find the domain and range of the following circles.

Use the results from question 5 to describe the process for finding the
domain and range of a circle given its center and radius
- (x-4)2 + y2 = 32
- (x+5)2 + (y-4)2 = 22
- (x-6)2 + (y-2)2 = 12
- x2 + (y-3)2 = 42
- (x-h)2 + (y-k)2 = r2
