I was given a graph, and i assigned an axis and plotted points. i have the max, min, principal axis, amplitude, and period but i dont know now how to make a function in A sin B(x-c) + D form.

Maximum - 6.45

Minimum - 1.00

Principal axis - 3.725

amplitude - 2.725

Period - 9.2

I uploaded a not exact picture of the graph, its the blue line.
