A. Translate left 4 units, and reflect across the x-axis to get g(x). B. Translate left 4 units, and reflect across the y-axis to get g(x). C. Translate right 4 units, and reflect across the y-axis to get g(x). D. Translate right 4 units, and reflect across the x-axis to get g(x). Choose the correct description for the transformation below.

Solution
To solve this transformation problem, let's break down the given functions:
We need to describe how to transform into .
Step-by-step Transformation:
-
Shift the function horizontally:
- The function is a cubic function that has been shifted right by 2 units (because of the ).
- To transform it into , we need to shift the graph left by 4 units (since is the horizontal translation).
-
Reflection:
- The negative sign in front of indicates a reflection across the x-axis.
Thus, the correct transformation to get from to involves:
- Shifting the graph left by 4 units.
- Reflecting the graph across the x-axis.
Answer:
A. Translate left 4 units, and reflect across the x-axis to get .
Let me know if you'd like more details or clarification. Here are a few related questions:
- What are the general rules for translating and reflecting cubic functions?
- How would the graph change if the reflection was across the y-axis instead?
- What happens if we shift the function up or down instead of left or right?
- How does the horizontal translation affect the overall behavior of cubic functions?
- What is the impact of negative coefficients in polynomial functions?
Tip: When analyzing transformations, always focus on the order: horizontal shifts, reflections, and vertical shifts in that sequence.
