12-67.
1. Write a possible equation for the graphs shown below. Then state the amplitude and period of the function. Describe how the graph relates to the parent function. Homework Help ✎

1. parent: y = sin(x)

2. parent: y = cos(x)

Look at the graph to determine the amplitude, period, phase shift, and vertical shift.

Use the information in y = a sin b(x + c) + d

$y=-2 \text{ sin}\left (\frac{1}{2}\left (x-\frac{\pi}{2}\right )\right )+1$
