Thread: shifting the graph of y=sin(x)

I know how to draw sine graphs and how to write the equation by looking at the graph but i have no idea what this question means, i have this on my homework, cant solve it.

"Find the equation of a sine wave that is obtained by shifting the graph of to the right 1 units and downward 8 units and is vertically stretched by a factor of 4 when compared to ."

y=AsinB(x+h) + k, i dunt know which is which variable?

Graph transformations must have been explained in class or in your textbook. These two tutorials also seem good.
