Question

3. A virus has infected 400 people in the town and is spreading to 25% more people each day.
Write an exponential function to model this situation, then find the number of people that will be
infected in 10 days.

Answer 1

Do you have to draw a diagram

Answer 2

The answer will be 1,400.

25% of 400 is 100.
You take the 100 and add it to the 400 each day.
After 10 days, you will have 100!!

The formula for an exponential function is f(x)=b^x.

I don’t remember exactly how to set up the problem...but I hope that helped!
