12-67.

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 ✎

parent:

*y*= sin(*x*)

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*
