A. (-2,3) because Rectangle ABCD is dilated by a scale factor of 1/2.
        
                    
             
        
        
        
Start from the parent function 
In the first case, you are computing

In the second case, you are computing
, you translate the function horizontally, 
 units left if 
 and 
 units right if 
.
On the other hand, when you transform 
, you translate the function vertically, 
 units up if 
 and 
 units down if 
.
So, the first function is the "original" parabola 
, translated 
 units right and 
 units up. Likewise, the second function is the "original" parabola 
, translated 
 units left and 
 units down.
So, the transformation from 
 to 
 is: go 
 units to the left and 
 units down
 
        
                    
             
        
        
        
A because radius is half of the diameter
