Question

PLEASE HELP!!The number of members of an online community increases each month. The function M(t) = N(1+r)t represents the number of members at month t, where N is the initial number of members and r is the rate of increase. Select the correct statement.

Answer 1

B

Explanation:

i just did it and it was right

Answer 2

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.
