Translations of Sinusoidal Functions
Part A: Horizontal Translations/ Shifts Recall: x says something yet does the exact opposite.
The graph of y = f (x + d) is obtained from the graph of y = f(x) translated _______________.
The graph of y = f (x - d) is obtained from the graph of y = f(x) translated ________________.
Example: Refer to for the questions that follow.
1. Use mapping notation to graph the function below.
2. State its period and amplitude.
3. State the domain and range of the transformed function.
