Question

The population P of an organism

is growing exponentially. Select all
the functions that could represent
the population.
A. P = 400(0.85)t
B. P = 2(1.35)t
C. P = 10(1.15)t
D. P = 215(0.95)t
E. P = 75(2.85)t
F. P = 900(0.05)t

Answer 1

Answer: B, C and E

Step-by-step explanation: the term growing means the value is increasing, and a number multiplied by 1 gives the same number; therefore in order for that number to increase, it need to be multiplied by a bigger number which is greater than 1, in this case it can not be a number less than 0 like 0.85, so all the number which are greater than 1 in the bracket are correct.

the number before the bracket is the population before increasing, so you can substitute any value for t and try out different outcomes, you will get only B, C and E as number greater than the original number
