D,the quadratic function turning point is (-2,-1) while the other graphs change direction at (-2,3)
Step-by-step explanation:
The point where the graph of a quadratic function changes direction is called a turning point.This is the point where the curve changes to face up or down according to the function.The functions in A,B and C have a common turning point (-2,3) that also appears in the table.The function in D has a turning point at (-2,-1) that is different from the other three functions.
