Answer:

The correct option is B.

Explanation:

The number of members of an online community increases each month. It is represented by the function


M(t)=N(1+r)^t

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
(1+r)^t. 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.
