Step-by-Step Solution

To determine if a decreasing function is possible with the two given points, we need to calculate the slope between them based on the common definition of a decreasing function.

Let's follow these steps:

  • Step 1: Identify the given points.
  • Step 2: Calculate the slope using these points.
  • Step 3: Verify that the slope is negative.

Step 1: The points appear to be roughly at coordinates near (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) according to their positions on the graph, with exact coordinates not provided, we'll assume accurate readings from the visual information.

Step 2: Calculate the slope using the formula:

slope=y2y1x2x1 \text{slope} = \frac{y_2 - y_1}{x_2 - x_1}

Given the visual interpretation:

x1<x2 x_1 < x_2 and y1>y2 y_1 > y_2 , so this ensures the change in yy is negative when divided by a positive change in xx.

Step 3: As the slope slope=y2y1x2x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1} is negative, the function represented by these points is decreasing.

Therefore, it is POSSIBLE to generate a decreasing function with the two given points.
