11-146.
  1. For each equation, state the amplitude, period, vertical shift, horizontal shift, and sketch two cycles of the graph. Homework Help ✎

    1. y = 3cos(2x)

The functions have the form of
y = a cos(b(xh)) + k.

Use 5 points to sketch one cycle and then repeat the pattern.
amplitude = 1
period = π
