To find the function
based on the transformations applied to
:
- Shift left 3 units: This changes
to . - Stretch vertically by a factor of 2: This transforms it to
. - Reflect across the
-axis: Now we have . - Shift down 1 unit: Finally, this leads to
.
Hence, the correct formula for
is
.
One might wonder why these transformations work as they do. The absolute value graph, with its characteristic V-shape, responds predictably to such shifts and stretches. It’s like giving the graph a “makeover” that makes it reflect its new position and orientation in the coordinate plane!
If you want to experiment further with transformations, consider graphing
and applying transformations step by step using graphing tools. It’s a fun way to visualize how each change affects the final graph!
