Math Problem Statement
Use the graph of y = f(x) to graph the function y = (1/2)f(-4 - x). For each point for f(x), determine the corresponding point for y = (1/2)f(-4 - x). Points on f(x) are: (-5, -1), (-4, 5), (0, 0), (1, -2), (2, 2).
Solution
We need to find the corresponding points for the transformation based on the given points from the graph of .
Step-by-Step Transformation:
- Horizontal reflection and shift: The term suggests a reflection across the y-axis and a horizontal shift by 4 units to the left.
- Vertical scaling: The outside the function scales the output (y-values) by a factor of 0.5.
Let’s apply this transformation to each point:

Point on | Point on |
---|---|
(-5, -1) | (1, -0.5) |
(-4, 5) | (0, 2.5) |
(0, 0) | (-4, 0) |
(1, -2) | (-5, -1) |
(2, 2) | (-6, 1) |
Would you like more details or have any questions on how the transformation works?
Here are five follow-up questions that expand on this concept:
- What is the effect of a horizontal translation on the graph of a function?
- How does vertical scaling impact the graph of a function?
- What happens when a function is reflected across the y-axis?
- Can you explain the difference between and in terms of horizontal shift?
- How would you graph compared to ?
Tip: Always apply transformations in the correct order: first handle the horizontal changes (inside the function), then vertical changes (outside the function).
