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:
x-intercept is -2 and y-intercept is -5
Step-by-step explanation:
You take the numbers that are above 5 and put them up one to the next tenth then you do that the same for thousands. your anwser would be 900,000
