Round 396.6 to 396, because 396/9=44, making a whole number. Hope this helps!!
First, conceptually understand what an inverse function is, it makes solving it very intuitive. An inverse function is simply a function which has points (y,x) for every point (x,y) of the parent function. So you are essentially taking all points of the parent function and switching the x and y coordinates for each. Those switched coordinates are produced by the "inverse function".
Mathematically then, finding the inverse function is a matter of solving for x and then switching the variable labels. In this case:
y=2x+1 subtract 1 from both sides
y-1=2x divide both sides by 2
(y-1)/2=x now just switch the labels for the variables...
y=(x-1)/2 so
f^-1(x)=(x-1)/2 is the inverse of f(x)=2x+1

Answer:
-Total amount Rafael ended up paying for the motorcycle: $25,186.2
-Interest: $1,586.2
Step-by-step explanation:
You can find the total amount Rafael ended up paying by adding up the down payment plus the result of multiplying the monthly payment for the number of months he paid:
Total payment=3,300+(364,77*60)
Total payment=3,300+21,886.2
Total payment=25,186.2
Now, to calculate the amount of interest that Raphael paid on the loan, you should subtract the price of the motorcycle from the total amount Raphael paid:
Interest=$25,186.2-$23,600
Interest=$1,586.2
