8-90.
  1. 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 ✎

    1. f(x) = –2sin(x) – 3

    2. 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.
