8-90.

Graph two complete cycles of each of the following trigonometric functions. Then state the amplitude, period, and any shifts or reflections of the graph. Homework Help ✎

*f*(*x*) = –2sin(*x*) – 3*f*(*x*) = 5cos(*π*(*x*– 5))

For each function, identify the amplitude, period, horizontal shift, vertical shift, and any reflection.

Then sketch the function. Check your sketch using a graphing calculator. Identify and correct any mistakes.
