1. Problem Description
We are given the transformed function , and we need to determine the transformations applied to the parent function . We need to identify the reflections, stretches/compressions, vertical shifts, and horizontal shifts.
2. Solution Steps
The general transformation of a function can be represented as .
Here, , so we have:
a) Reflections: The negative sign in front of (i.e., ) indicates a reflection over the x-axis.
b) Stretches/Compressions: The absolute value of is . Since , there is a vertical stretch by a factor of . Since , there is no horizontal stretch or compression.
c) Vertical Shifts: The term indicates a vertical shift downwards by 2 units.
d) Horizontal Shifts: The term indicates a horizontal shift to the right by 4 units.
3. Final Answer
a) Reflection over the x-axis.
b) Vertical Stretch by a factor of
3. c) Vertical Shift down by 2 units.
d) Horizontal Shift right by 4 units.
