Answer:
The population after 15 years will be ![694,835\ people](https://tex.z-dn.net/?f=694%2C835%5C%20people)
Step-by-step explanation:
In this problem we have a exponential function of the form
![f(x)=a(b^{x})](https://tex.z-dn.net/?f=f%28x%29%3Da%28b%5E%7Bx%7D%29)
where
a is the initial value
b is the base
r is the rate
b=(1+r)
x ----> the number of years
f(x) ----> the population
we have
![a=400,000\ people](https://tex.z-dn.net/?f=a%3D400%2C000%5C%20people)
![r=3.75\%=3.75/100=0.0375](https://tex.z-dn.net/?f=r%3D3.75%5C%25%3D3.75%2F100%3D0.0375)
![b=1+r=1+0.0375=1.0375](https://tex.z-dn.net/?f=b%3D1%2Br%3D1%2B0.0375%3D1.0375)
The equation is
![f(x)=400,000(1.0375^{x})](https://tex.z-dn.net/?f=f%28x%29%3D400%2C000%281.0375%5E%7Bx%7D%29)
For x=15 years
substitute the value of x
![f(x)=400,000(1.0375^{15})](https://tex.z-dn.net/?f=f%28x%29%3D400%2C000%281.0375%5E%7B15%7D%29)
![f(x)=694,835\ people](https://tex.z-dn.net/?f=f%28x%29%3D694%2C835%5C%20people)
therefore
The population after 15 years will be ![694,835\ people](https://tex.z-dn.net/?f=694%2C835%5C%20people)

Answer:
1.25
Step-by-step explanation:
f(5) = <span> -2(5)^2 + 2(5) -3
f(5) = -50 + 10 - 3
f(5) = -43
