Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.

This is an example of an exponential equation. These equations are always in the form y = ab^x.

The a value is the starting value. The b value is the interest rate. The x value is the number of years.

The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.

What is the form of an exponential equation.?

The exponential equations are always in the form

[tex]y = ab^x.[/tex]

a = The starting value.

b =The  interest rate.

x  =The number of years.

The only thing to be careful about is the rate.

We are adding 1.25%

1.25/100=0.125

Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.

Therefore we get,

The function that modes this situation is y = 475(1 + .0125)^x.
