Can someone help me finish these functions for these graphs?

These are the two graphs in question. I know the first graph has a midline of 8 and an amplitude of 8 but the period and the phase shift are what is really difficult for me.
As for the second graph is a bit harder since it doesn't have many definitive points on the graph. Even the midline and amplitude are bugging me since its y != 9 when x = 0. the endpoints are -12 and 12 with the peak of the graph being x=10 and min being x = 2.

Are you the same person I answered before?
