Assuming that you are studying real valued functions of real numbers, the answer is Yes if #0# is in the domain of #f#.

Explanation:

#f# is odd if and only if #f(-x)=-f(x)# for all #x# in the domain of #f#.

If #0# is in the domain of odd function #f#, then #f(-0) = -f(0)#.
But #-0=0# so #f(0)=-f(0)#.
This implies #f(0)=0#

Note that #f(x) = 1/x# is an odd function with #0# NOT in the domain.
