Solución
To perform a horizontal shrink by a factor of
on the function
, follow these steps:
Understanding Horizontal Shrink
A horizontal shrink by a factor of
involves compressing the graph of the function towards the y-axis by multiplying the input
by
. Specifically:
- Shrink Factor (
): - Transformation Rule: Replace
with or equivalently .
Applying the Transformation
Given:
-
Determine the Transformation:
- Shrink factor
implies .
- Shrink factor
-
Replace
in the Function: -
Simplify the Expression:
Resulting Function
After performing a horizontal shrink by a factor of
, the transformed function is:
Graphical Interpretation
-
Original Function
: - V-shaped graph with a vertex at
. - Steeper slopes due to the coefficient 2 inside the absolute value.
- V-shaped graph with a vertex at
-
Transformed Function
: - Vertex remains at
. - Even steeper slopes due to the increased coefficient 4, indicating a greater horizontal compression.
- Vertex remains at
Visualization
Here’s how the functions compare:

After Horizontal Shrink:

Note: The image above is a placeholder. When plotting, you’ll see that the transformed function
is narrower than the original
due to the horizontal shrink.
Summary
- Original Function:
- After Horizontal Shrink by
:
This transformation compresses the graph horizontally by a factor of
, making it steeper and narrower.

Extra Insights
When you apply a horizontal shrink to the function
, you effectively replace
with
in the function. This means your new function becomes
. This transformation makes the graph of the function narrower, increasing the rate at which it changes as
moves away from the origin.
In real-life applications, understanding how such transformations work can be extremely useful, especially in fields like engineering or economics where modeling growth or optimization problems often requires adjusting functions. For instance, if this function represented profit over time, squeezing it horizontally could symbolize a faster rate of profit increase due to improved efficiency!
