Step-by-step explanation: I'm not really sure how to explain it, but I'm almost 100% sure that's the right answer.
Answer:
around 120
Step-by-step explanation:
So, here we have an exponential function.
Remember that an exponential function has the form:

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

So,

For city B:

But something different happens with city C. This is not an exponential function, this is a linear function.
So,

Answer:
In M/n(x) x cannot be 0
Step-by-step explanation:
If any number is divided by 0, then that number is undefined and has no answer, so in math this is always avoided by not dividing with 0.
