Under ideal conditions, the population of a certain species doubles every nine years. If the population starts with 100 individuals, which of the following expressions would give the population of the species t years after the start, assuming that the population is living under ideal conditions? A) 2 x 100^9t
B) 2 x 100^t/9
C) 100 x 2^9t
D) 100 x 2^t/9​

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

ok

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
