Is it possible to generate a decreasing function with the two given points?
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: The points appear to be roughly at coordinates near and 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:
Given the visual interpretation:
and , so this ensures the change in is negative when divided by a positive change in .
Step 3: As the slope is negative, the function represented by these points is decreasing.
Therefore, it is POSSIBLE to generate a decreasing function with the two given points.
Possible
Is the function in the graph decreasing?
Look at the direction! If the right point is lower than the left point, the function decreases between them. Check: does y get smaller as x gets bigger?
A slope of zero means the function is constant (neither increasing nor decreasing). The line would be perfectly horizontal between those two points.
You can connect any two points with some function! The key question is whether that connection has a negative slope (decreasing) or positive slope (increasing).
For this type of problem, you just need to see the relative positions. Is the right point lower than the left point? Then it's possible to create a decreasing function!
Students often overthink it! You don't need complex calculations - just use the basic slope concept: negative slope = decreasing function.
