The cosine wave gets expanded in both + and -
y-directions by the factor of +3+
------------
The phase of the cosine wave gets shifted by almost
+pi+=+3.141+ ( if +x+ is in radian measure )
--------------------------------------------
Here's the plot:
+graph%28+600%2C+300%2C+-10%2C+10%2C+-5%2C+6%2C+3%2Acos%28+x%2B3+%29%29+
At +x+=+0+, the cosine would normally be +3+,
but it is almost +-3+ due to +3 phase shift
