Answer:
0
Step-by-step explanation:
32=32+0
To answer the question above we first need to know how much is the interest per year. In equation, 3% of $2500 is 75. 75 per year in 4 years is 300. So add $300 to the principal amount, the money after 4 years would be $2800.
For this case we must find the inverse of the following function:

For this, we follow the steps below:
We change f (x) to y:

We exchange the variables:

We solve for y:

We divide between 8 on both sides of the equation:

We raise both sides of the equation to the square to remove the root:

So, the inverse is:
