For the Problem identify all of these that are relevant: the period, the amplitude, vertical shift and horizontal shift. Then sketch a graph of the function over one period. Be sure to label the axes appropriately.

d(x) = 2 cos (1/4 x) – 1

anonymous · Answer

cosine

dumbcow · Answer

y = Acos[b(x-h)] +k
A is amplitude
period is 2pi/b
h is horizontal shift
k is vertical shift
