Answer

Explanation:

Step1: Recall function - value and derivative meaning

The value of $f(x)$ at a point is the $y$ - coordinate of the point on the graph. The sign of $f^{\prime}(x)$ is determined by the slope of the tangent line at the point.

Step2: Analyze point A

At point A, the $y$ - coordinate is above the $x$ - axis, so $f(x)$ is positive. The slope of the tangent line at point A is negative, so $f^{\prime}(x)$ is negative.

Step3: Analyze point B

At point B, the $y$ - coordinate is below the $x$ - axis, so $f(x)$ is negative. The slope of the tangent line at point B is negative, so $f^{\prime}(x)$ is negative.

Step4: Analyze point C

At point C, the $y$ - coordinate is below the $x$ - axis, so $f(x)$ is negative. The slope of the tangent line at point C is zero (horizontal tangent), so $f^{\prime}(x)$ is zero.

Step5: Analyze point D

At point D, the $y$ - coordinate is above the $x$ - axis, so $f(x)$ is positive. The slope of the tangent line at point D is zero (horizontal tangent), so $f^{\prime}(x)$ is zero.

Step6: Analyze point E

At point E, the $y$ - coordinate is above the $x$ - axis, so $f(x)$ is positive. The slope of the tangent line at point E is negative, so $f^{\prime}(x)$ is negative.

Answer:

At point A: $f(x)$ is Positive, $f^{\prime}(x)$ is Negative At point B: $f(x)$ is Negative, $f^{\prime}(x)$ is Negative At point C: $f(x)$ is Negative, $f^{\prime}(x)$ is Zero At point D: $f(x)$ is Positive, $f^{\prime}(x)$ is Zero At point E: $f(x)$ is Positive, $f^{\prime}(x)$ is Negative
