Answer:
f^-1(x) = √(6/(9 -x))
Step-by-step explanation:
The inverse function is the solution to ...
x = f(y)
x = 9 -6/y^2
x +6/y^2 = 9 . . . . . add 6/y^2
6/y^2 = 9 -x . . . . . subtract x
6/(9 -x) = y^2 . . . . . multiply by y^2/(9 -x)
y = √(6/(9 -x)) . . . . take the square root
Then the inverse function can be written as ...
f^-1(x) = √(6/(9 -x)) . . . . . . x < 9
Answer: $55.50
$9.25 * 6 = $55.50
Hope this helps let me know if you have any questions. Have a great day!
Ben - 3/8
RV - 1/8
Total = 80
Ben = 3/8 ( 80 ) = ( 3 ) ( 10 ) = 30 cars
Rv = ( 1 / 8 ) ( 80 ) = ( 10 ) = 10 cars
Ben's have sold 20 cars more than RV
Hope helps!
