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?
