Answer
Explanation:
Step1: Recall turning - point concept
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
From the table, the function values change from positive to negative between $x=-2$ and $x = 0$. The function value at $x=-2$ is $0$ and at $x = 0$ is $-2$. Before $x=-2$, $f(x)$ is non - negative and after $x=-2$ it becomes negative. So, $(-2,0)$ is a possible turning point.
Answer:
$(-2,0)$
