Question Analysis
This problem assesses the ability to construct the equation of a transformed tangent function given specific transformations.

Key Concept Explanation
The general form of a transformed tangent function is . The period is given by , the phase shift by , and the vertical shift by .

Step-by-step Solution
1. Given the period is , solve for : .
2. Given the phase shift is to the left, (since it is to the left, the sign is negative).
3. Given the vertical shift is 4 units up,
