Step-by-step explanation:
Since the dot in the illustration isn't filled in, that means that x can not be a part of -14, which means it is greater than 14
At day 0 the height of the plant = 12 cm
Calculate how many days to get to 16.13 cm:-
16.13 = 12(1.03)^n
1.03^n = 16.13 / 12 = 1.34417
n = ln 1.34417 / ln 1.03 = 10 days
I would think that a reasnable domain would be 0 =< n <= 100
