as usual,
amplitude = 1/2
period = 2π/π = 2
The - sign doesn't mean anything here, since cos(-x) = cos(x)
A little confused on this one...
Find the amplitude and the period of h(x) = 1/2 cos (-πx).

I was thinking that was the answer, but I just wasn't sure if those pi's were going to cancel out. Thanks for the confirmation! :)
