Question Analysis
This question tests the student's understanding of performing multiple reflections on a linear function. The original function is given, and the student must apply the rules for y-axis and x-axis reflections in sequence.
Key Concept Explanation
Reflection about the x-axis: For a function , reflecting it about the x-axis changes the sign of the output (y-value). The resulting function is .
Reflection about the y-axis: For a function , reflecting it about the y-axis changes the sign of the input (x-value). The resulting function is .
