Kathy, you can follow the techniques that I have listed for you. It’s the same techniques, but I simplified it.

In short, you need the following

Max
Centre
Min
Number of cycles
Starting point and direction

to draw the un-modulused graph.

Once you are able to list these five things, you can draw the graph. It’s always the same shape, just the position and the values of the max/min may be different.

Q4 and Q5; Q5 requires a great deal of imagination and understanding of the shifting of the graph (i.e. vertical shift) and how it works.
