What is the y = –3x2 – 12 Axis of symmetry:

This equation y=3x2+12x−2 is in standard form, or ax2+bx+c . To find the axis of symmetry, we do x=−b2a . We know that a=3 and b=12 , so we plug them into the equation. So the axis of symmetry is x=−2 .

Step-by-step explanation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
