In the quadratic function, the turning point is the point that divides the curve into equal parts
That means the value of all y-coordinates before the turning point is equal to the values of y-coordinates after the turning point.
Since the turning point is (2, 1)
Then the missing y-coordinate in point (0, ---) is the same as the y-coordinate of the point after point (3, 2)
So I need to see the missing part in the table to give you the answer
If the missing part is (4, 5), then
The answer is 5
Answer number (4)
