SOLUTION
Step 1 ;
In this question, we are meant to examine the graph of the function,
[tex]f\text{ ( x ) = 3 sin ( }\frac{1}{2}\text{ x )}[/tex]We also to know the sketch of the graph of f ( x ) and
the translation y ( x ) = f ( x + 1 )
Step 2 :
The graph is as shown below:
CONCLUSION: OPTION A IS VERY CORRECT.
