Examine the following graph, where the exponential function P(x) undergoes a transformation.The preimage of the transformation is labeled P(x), and the image is labeled I(x).


Explanation
For the function P(x), the value of x in the function is halved to get the values of x in the image.
This can be seen in the graphs below.
The red line represents the preimage and the blue line represents the image.
Answer: Option 4
