Step-by-step explanation:
Given
New function: 
We can assume the parent function to be:

The new function can be represented as:

Where
A = Vertical stretch factor
B = Period
C = Right shift
By comparison:
to 



Solve for B

Using the calculated values of
This implies that, the following transformations occur on the parent function:
- <em>Vertically stretched by </em>
<em /> - <em>Horizontally compressed by </em>
<em /> - <em>Right shifted by </em>
<em />
