What does log(0) equal?

1 Answer

Jul 18, 2015

#log(0)# is undefined.

Explanation:

Basically you are trying to find a value of #x# such that #e^x = 0#.

As a real valued function #e^x# maps #(-oo, oo)# to #(0, oo)#, so its inverse, #log#, maps #(0, oo)# to #(-oo, oo)#.

#log(x)# is undefined for #x <= 0#
