Sinusoidal Function Transformations
1. Below is the graph of a sinusoidal function, with angles measured in degrees.
1 a)
What is the domain of the function?
1 b)
What is the range of the function? Then what is the amplitude?
1 c)
What is the period of the function? [Don't forget the units.]
1 d)
What is the axis of the curve of the function? (i.e. the horizontal line halfway between the max and the min)
1 e)
What is the phase shift of the function? Did you compare to the sine or cosine function? [Make sure to use "right" or "left" in your answer.]
1 f)
State the equation of the function in the form or .
2. Describing the properties of a sinusoidal function given its equation.

2 a)
What is the range and domain of the function?
2 b)
What is the amplitude of the function?
2 c)
What is the period of the function?
2 d)
What is the phase shift of the function?
