Answer:
The correct option is B.
Step-by-step explanation:
The number of members of an online community increases each month. It is represented by the function
[tex]M(t)=N(1+r)^t[/tex]
Where N is the initial number of members and r is the rate of increase.
The initial value for the function is N, because at t=0 the value of M is N. So, option A is incorrect.
The value of M is product of N and [tex](1+r)^t[/tex]. The second term is free from N, because second term does not contain N. therefore the second factor does not depend on N. So, option B is correct.
It is an exponential growth function, therefore it can not be linear. So, option C is incorrect.
The initial value is constant. In the given function only the value of t can be changed. So, option D is incorrect.
