Answer
Explanation:
Step1: Recall turning - point definition
A turning point of a continuous function is a point where the function changes from increasing to decreasing or vice - versa.
Step2: Analyze function values
The function values are $f(-6)=8$, $f(-4)=2$, $f(-2)=0$, $f(0)= - 2$, $f(2)=-1$, $f(4)=0$, $f(6)=4$. The function is decreasing from $x=-6$ to $x = 0$ ($8\rightarrow2\rightarrow0\rightarrow - 2$) and then starts increasing from $x = 0$ to $x=6$ ($-2\rightarrow - 1\rightarrow0\rightarrow4$).
Answer:
$(0, - 2)$
