How does the graph [tex] y=-3 \cos (2\theta+ \frac {\pi} {4}) +3 [/tex] Differ from the graph of [tex] y=\cos\theta [/tex]
I think this graph is different because it has a vertical stretch by a factor of 3 and is translated upwards 3 units but I am not sure how to rearrange this to find the horizontal translation and the horizontal compression/stretch
Could someone please help me out! THANKS
