Answer:



Step-by-step explanation:
From the attachment, we have:



Rotation: 180 degrees clockwise
Required
Find J', K' and L'
When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)
So, we have:



 
        
             
        
        
        
Answer:
 B)max/ opens down
Step-by-step explanation:
Parabola equation:
The equation of a parabola has the following format:

If  , that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
If  , that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
In this question:

From the graph, we already see that it opens down and has a max, and analitically, since  , this is confirmed. The correct answer is given by option b.
, this is confirmed. The correct answer is given by option b.
