this one seemed especially heinous ;)
find the equation of a cosine wave that is obtained by shifting the graph of y=cos x to the left 1 unit and upward 3 units and that is horizontally compressed by a factor of 2 when compared to y=cos x

To shift right or left, add to the x value before doing the function.
To shift up or down, add to the y value, after doing the funtion.
To compress in the x direction, multiply the x value before doing the function.
The only question is whether the horizontal shift or the horizontal compression is first.
In this example:
y=cos(2(x+1) + 3 works nicely
