if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.

Answer:
27,000
Step-by-step explanation:
We have been given that after a dose of an antibiotic, the number of bacteria decreases. The equation is models this "decay" situation. We are asked to find the original number of bacteria.
We know that an exponential decay function is in form , where,
y = Final value,
a = Initial value,
b = Decay factor,
x = Time.
Upon looking at our given equation, we can see that initial value is 27,000, therefore, 27,000 represents the original number of bacteria.
