Draw the graph of the following functions:
(i) f(x)= x-[x] for all x belongs to [-3,3]

(ii) f(x)= {1/x if x<0 and -1/x if x>0

Please explain me with step by step...!
Please tell me as soon as possible...!

You can simply put in some values in the x to get some points and then join them together.

Define [x], start to subtracting operation, you will get new function consist of x-[x] in that's a moment will be easy to graph it in the coordinate plane.
