See explanation.

To draw the graph of this function you kave to draw the graph of $y = cos x$ $y=cosx$

graph{cosx [-7, 7, -2, 2]}

and translate it by a vector $[π; 0]$ $[pi;0]$ (i.e. move the graph $π$ $pi$ units to the right)

graph{cos(x-pi)[-7,7,-2,2]}

How do you graph y=cos(x−π)y=cos(x-pi)?
