# Compare y=Cos(x) and transformation HELP

How does the graph $$y=-3 \cos (2\theta+ \frac {\pi} {4}) +3$$ Differ from the graph of $$y=\cos\theta$$

I think this graph is different because it has a vertical stretch by a factor of 3 and is translated upwards 3 units but im not sure how to rearrange this to find the horizontal translation and the horizontal compression/stretch
