1. Problem Description
The problem asks to identify the type of transformation applied to the parent function to obtain the function . The options are reflections, stretches/compressions, vertical shifts, and horizontal shifts.
2. Solution Steps
The transformation is given by the equation .
This transformation adds a constant value (9) to the output of the function .
Adding a constant to the output of a function results in a vertical shift. If the constant is positive, the shift is upwards. If the constant is negative, the shift is downwards.
In this case, since we are adding 9 to , the graph of is shifted upwards by 9 units.
Vertical shifts are described by transformations of the form , where is a constant. If , the graph shifts upwards by units. If , the graph shifts downwards by units.
Reflections across the x-axis are described by .
Reflections across the y-axis are described by .
Horizontal stretches/compressions are described by for some constant .
Horizontal shifts are described by , where is a constant.
Since we have , this is a vertical shift of the parent function .
3. Final Answer
The transformation is a vertical shift.
Specifically, it is a vertical shift upwards by 9 units.
The answers for each option are:
a) Reflections: No.
b) Stretches/Compressions: No.
c) Vertical Shifts: Yes, upwards by
