#"Domain:"# #t>=0#

#"Range":# #N(t)>=N_0#

Explanation:

The domain of this function is all the possible values that #t# can take. Since #t# is a measure of time, we know it has to be positive since there can't be a negative amount of hours.

The range of this function is total population, #N(t)#, after #t# hours. Since it started at #N_0#, this is the least value it can take because the cells are doubling so the number of cells has to increase.
