Math Problem Statement
Below is the graph of y = f(x). Using the red points to draw the graph of y = -\frac{1}{2}f(x).
Solution
The image is a problem about function transformations. The graph of is given, and the task is to draw the graph of .
To solve this problem, we need to understand how the given transformation affects the original graph:
- Reflection across the x-axis: The negative sign in indicates a reflection over the x-axis. This means that every point on the graph of will be mirrored across the x-axis.
- Vertical compression by a factor of : The factor indicates a vertical compression. This means that the y-coordinates of all points on the reflected graph will be halved.
Steps to Draw the Graph:
- Identify the key points on the original graph . Let's assume we have points like , , etc.
- Apply the reflection across the x-axis: Each point will become .
- Apply the vertical compression: Multiply the y-coordinates by . The reflected points will transform from to .
Applying the Transformation to Each Point:
- Take each point from the graph of and apply the transformations described above.
- Plot these new points on the coordinate plane to draw the graph of .
Would you like a more detailed explanation or have any questions about this transformation process?
Here are some related questions to explore:
- What happens if the transformation was instead?
- How does a horizontal stretch or compression affect the graph?
- What is the effect of a translation of the function, such as ?
- How would the transformation change if the expression was ?
- How can we determine the new range of the function after applying transformations?
Tip: Understanding each transformation (reflection, vertical/horizontal stretch, and translation) separately can help in combining them correctly to draw the transformed graph accurately.
