Hi!
So for this you need an equation. It will be 72 • 0.8 - 2.88 • 3
this is bc 12 x 6 is 72 and 3 bc 2 x 3 is 6.
so after you solve it you should get : $48.96..Hope this helped! :))

Answer: 6</h3>
===================================================
Explanation:
Each point listed is of the form (x,y)
The input x is fed into the f(x) function to get a y = f(x) output.
Recall that the inverse function undoes everything the original function does.
This means that when we determine the inverse function for a list of points like this, we just swap each x and y.
So if
![f = \{ (3.5, 2), (0,4), (1,5), (6,1) \}](https://tex.z-dn.net/?f=f%20%3D%20%5C%7B%20%283.5%2C%202%29%2C%20%280%2C4%29%2C%20%281%2C5%29%2C%20%286%2C1%29%20%5C%7D)
then,
![f^{-1} = \{ (2,3.5), (4,0), (5,1), (1,6) \}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%3D%20%5C%7B%20%282%2C3.5%29%2C%20%284%2C0%29%2C%20%285%2C1%29%2C%20%281%2C6%29%20%5C%7D)
Again all I've done is swap each x and y value.
From here, we look through the inverse function set and look for the point when x = 1. We see the point (1,6) is in the set.
Therefore, ![f^{-1}(1) = 6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%281%29%20%3D%206)
