Math Problem Statement

Position points A and B so they both lie on the graph of (f + g)(x).

Solution

It looks like the image presents two functions, f(x)f(x) and g(x)g(x), along with the graph of their sum (f+g)(x)(f + g)(x). The task is to position points AA and BB on the graph such that they both lie on the graph of (f+g)(x)(f + g)(x).

Let me guide you through this:

  1. Graph of (f+g)(x)(f + g)(x): The graph of f(x)+g(x)f(x) + g(x) is obtained by adding the yy-coordinates of the functions f(x)f(x) and g(x)g(x) for each xx-value. You would look for the points on the graph where the sum of their yy-coordinates match the values of AA and BB.

  2. Positioning of Points AA and BB: The coordinates of these points need to satisfy the equation of (f+g)(x)(f + g)(x). By visually identifying the graph of f(x)f(x) and g(x)g(x), you can then find the points where their sum matches the positions of AA and BB.

Would you like me to calculate or explain how to find exact points for AA and BB? If you'd prefer, I can walk you through the detailed steps of how to analyze this situation.


Here are five questions related to this:

  1. How do you calculate the point-wise sum of two functions on a graph?
  2. What are the key visual differences between the graphs of f(x)f(x) and g(x)g(x) in this image?
  3. How does the behavior of f(x)+g(x)f(x) + g(x) change compared to f(x)f(x) and g(x)g(x)?
  4. What specific coordinates would you choose for AA and BB to match the graph of (f+g)(x)(f + g)(x)?
  5. How can you algebraically verify that points AA and BB lie on the graph of (f+g)(x)(f + g)(x)?

Tip: When adding two functions graphically, always align their corresponding xx-values and sum their yy-values.
