Answer:
x -3 -2 -1 0 1 2 3
y 28 19 12 7 4 3 4
Step-by-step explanation:
The point where the quadratic function changes direction (which is the maximum or the minimum of the function) is called the turning point. In options A, B and C the turning point is at (-2, 3), and in option D the turning point is at (-2, -1).
Given that all of them correspond to the same x-value and options A and B are the same, I assume one of them was mistyped. Given the following option:
x -3 -2 -1 0 1 2 3
y 28 19 12 7 4 3 4
we see that the turning point is at (2, 3) which represents a different x-value.
