1. Problem Description
We are given the transformed function and we want to determine the transformations that have been applied to the parent function . We need to identify any reflections, stretches/compressions, vertical shifts, and horizontal shifts.
2. Solution Steps
* Reflection: The general form for a reflection across the x-axis is and a reflection across the y-axis is . In our function, , there is no negative sign in front of or a negative inside the as in , thus there is no reflection.
* Stretches/Compressions: The general form is , where is a constant. If , then it's a vertical stretch. If , then it's a vertical compression. In the function , the constant . Since , there is a vertical compression by a factor of .
* Vertical Shift: The general form is , where is a constant. If , then the graph shifts upward. If , then the graph shifts downward. In the function , we have , so there is a vertical shift downward by 5 units.
* Horizontal Shift: The general form is , where is a constant. If , then the graph shifts to the right. If , then the graph shifts to the left. In the function , we have . Here, , so the graph shifts to the right by 6 units.
3. Final Answer
a) No Reflection
b) Vertical Compression by a factor of 1/8
c) Vertical Shift Down 5 units
d) Horizontal Shift Right 6 units
