Graphing Sine and Cosine Functions with Phase Shifts (6.5.1)

Question 1

• A phase shift is a horizontal translation of a trig function.
• Phase shifts occur when adding or subtracting from the x-term in the trig function.
• A phase shift will move the graph of the function to the left or the right, depending on whether the constant is added
or subtracted.
• Adding or subtracting an entire period does not change the appearance of the graph.
