Not sure what the question is. You could plot it manually or use plotting software like Excel.

The period is 2π/(π/4) = 8
on the x-axis mark off 8 units, and split that into 4 equal parts.
draw an outline of a standard cosine curve using those divisions with an amplitude of 4
Now draw the reflection of your first curve in the x-asis
At this point you have y = -cos (π/5)x
no shift that last curve 1 unit to the right
you now have y = -cos π/5(x-1)
finally raise this curve up 3 units to get your final graph.
You might want to complete the curve to go from 0 to 9
