Answer:

y=-3x2 - 12x+6 , x = -(-12)/2*3 = 2 this one has axis of symmetry x = 2

Step-by-step explanation:

y = 3x² + 12x+6 : x = -12/6 = -2

y = 3x2 - 6x+12 , x = -(-6)/2*3 = -1

y=-3x2 - 12x+6 , x = -(-12)/2*3 = 2 this one

y=-3x2 + 12x+6 , x = -12/2*3 = -2

Harman [31]

Step-by-step explanation:

5x^2 - 20x + 20 = 5x^2 - 20x + 20
