Answer:
-22.4+12.8
Step-by-step explanation:
If the temperature started at 22.4 below zero you would write that as -22.4 because it had risen 12.8 degrees you would add those 12.8 degrees to -22.4
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
