y=-3sin (x-pi/4)+1 

First we draw the graph of 

y = sin(x)



Then we draw the graph of y = 3sin(x) which stretches it three times as high
and low



Then we draw the graph of y = -3sin(x) which reflects the graph in the y axis



Then we draw the graph of y = -3sin(x-pi/4) which shifts it right by pi/4 units.

But to do that we take each of the 5 main points, 0,,, and  and add  to each"

 = 
 =  = 
 =  = 
 =  = 
 =  = 




Then we draw the graph of y = -3sin(x-pi/4)+1 which shifts the graph up 1 unit.
