Graphing a function over two period interval

[coooool222]

I dont understand when they say graph each function over a two-period interval does that mean two cycles?
For example y = sin 1/2x . The period is 4 pi so what does it mean two period interval?

i got the key points but I cant figure out what two-period interval means

Yes, 2 cycles. E.g. from 0 to 8pi. Or 1pi to 9pi.

So can it also be from 0 to 4 pi and 0 to -4pi?

Yes, from -4pi to 4pi.
