Math Problem Statement
Solution
To solve the given problem, we need to transform the graph of the function based on the given transformation .
Step-by-Step Explanation
-
Understanding the Original Graph: The original graph, , includes the following key points:
- These points define the important features of the graph, including peaks, troughs, and intersections with the x-axis.
-
Transformation Breakdown: The transformation includes several operations:
-
Horizontal Compression (by a factor of 2): The term means that all x-coordinates are compressed towards the y-axis by a factor of 2. This halves the x-coordinates of all points.
-
Vertical Stretch (by a factor of 3): The term implies that the graph is stretched vertically by a factor of 3. Additionally, the negative sign reflects the graph about the x-axis.
-
Vertical Shift (upward by 4 units): The term shifts the entire graph upward by 4 units.
-
Applying the Transformation to Key Points:
Let's now apply these transformations to each key point on the original graph.
-
Point :
- Horizontal Compression: New x-coordinate =
- Vertical Stretch and Reflection: New y-coordinate =
- Vertical Shift: New y-coordinate =

Final Result:
The transformed graph of includes the following points:
You can now plot these points and sketch the transformed graph. The graph will be a vertically stretched, reflected, and shifted version of the original, with the same basic shape but modified based on the transformation.

Related Questions:
- How does horizontal compression affect the graph of a function?
- Why does multiplying the function by a negative constant reflect the graph about the x-axis?
- How does a vertical stretch differ from a vertical shift in terms of transformations?
- What are other examples of function transformations that change both the x- and y-coordinates?
- How would the graph change if the transformation was instead?
Tip:
Always apply transformations in the correct order: handle horizontal changes (like compression/stretch) first, followed by vertical changes (like stretch/reflection), and finish with shifts.
