2-129.

Graph two complete cycles of each of the following functions

Sketch a sine function shifted down

units. Do not scale the axes to begin with. This function has a period of

, so add a scale to your axes to match this characteristic as well as the amplitude.

Follow a process similar to the steps given in part (a).

This time begin by sketching a cosine function that is shifted to the left.
