Domain and Range

Hello. I'm having a little trouble finding the range of a function. The function is f(x) = arccos(x). I found that the domain is [-1,1] but I'm having a little trouble finding the range. I know that the range is [0,x], but I can't find x. x isn't infinity either as I tried. Thank you for help.
