Answer:
C
Step-by-step explanation:
If the average wasn't shifted at all, that means the third value must've been the same as the average to not shift it.
Your answer is -2 as the axis of symmetry is at -b/2a. So if you were to expand the equation, you would get y= x^2/4 +x -6 where b is 1 and 2a is ½ . Therefore -1 / ½ gives you -2
Answer: The answer is 81.

➷ Substitute the x and y values into the equation:
y = mx + c
'm' is the slope, which we know is 4
-10 = 4(3) + c
- 10 = 12 + c
c = -22
The equation is y = 4x -22
