Answer:
centered at (5,-3)
radius of 14 units
Step-by-step explanation:
A linear transformation will be the opposite of what contained in the parentheses( (x-5)^2 will be a regular line x but +5 units along the axis.
Therefore the variables contained in the parentheses will then correspond to the transformation, so it will be shifted +5 units along the x and -3 units along the y.
The radius is simply the answer square rooted which is 14 units in this case.
