graph two periods of the given cosecant or secant function:

We need to draw the graph of
[tex]y=2\sec (x+\pi)[/tex]It is the same with the graph of the parent function sec x with horizontal translation by pi
2 periods means the graph must be from 0 to 4pi
The purple graph shows the parent function sec(x)
It is stretched by a factor of 2 and translated pi units to the left
