Math Problem Statement
Solution
The problem asks to describe the transformations necessary to convert the graph of into that of .
Step-by-step breakdown:
-
Reflection: The function produces a V-shaped graph that opens upwards. In , the negative sign in front of the absolute value reflects the graph across the x-axis. This changes the graph from opening upwards to opening downwards.
-
Translation: The "+2" outside the absolute value indicates a vertical translation. The entire graph is shifted up by 2 units.
Conclusion:
The transformation involves reflecting the graph across the x-axis and then translating it up 2 units.
Thus, the correct answer is:
- Reflect across the x-axis, translate up 2 units.
