Analyzing slopes Use the points A, B, C, D, and E in the following graphs to answer these questions. <IMAGE>
a. At which points is the slope of the curve negative?

Verified step by step guidance

1. Step 1: Understand that the slope of a curve at a point is determined by the derivative of the function at that point. A negative slope indicates that the function is decreasing at that point.
2. Step 2: Identify the points on the graph where the curve is sloping downwards as you move from left to right. These are the points where the slope is negative.
3. Step 3: Examine the graph visually or use the derivative function if available to determine the slope at each point A, B, C, D, and E.
4. Step 4: For each point, check if the tangent line to the curve at that point has a negative slope. This can be done by observing if the tangent line is angled downwards from left to right.
5. Step 5: List the points where the slope is negative based on your observations from the graph or calculations from the derivative.
