I do not know what you are talking about with the first one. It is nott an equation
the second one is a circle with center at (3,7) and radius of 0.50
√3-(x-6)^2 + 15
What are the transformations in this? Confused by the three.
(x -3)^2 + (y - 7)^2 =.25
Is there a transformation on the radius?
Or just the center?

yes, so what are the actual transformations of the circle ? I know that it moves up 7 units and to the right 3. Does the radius/diameter of it have any separate transformation? And shouldn't the radius be .25/2? Not multiplied by 2? How is it not an equation? I was wondering about is it a horizontal compression of 3 or is it a shift?
no, the radius is the radius
it is r^2 = 0.25
so
r = 0.50
(x-k)^2 + (y-h)^2 = r^2
center at (h,k)
radius of r
it is r^2 = 0.25
so
r = 0.50
(x-k)^2 + (y-h)^2 = r^2
center at (h,k)
radius of r
NOT multiplied by 2
radius SQUARED on the right
r times r
radius SQUARED on the right
r times r
ok, so the radius is separate from the transformations. They got to the radius squared by .5^2.
