Answer:

Explanation:
The base of the tangent functions is 
 .
.
This is also called the parent tangent function that has a period of 
 .
.
The transformation that stretches the graph of 
 horizontally by a factor of B is
 horizontally by a factor of B is 

From the question, the basic tangent function was stretched horizontally by a factor of 10.
This implies that 

The equation of the transformed function is 

The period of this function is
