Answer:
![(a)\ f^{-1}(-15) = -6](https://tex.z-dn.net/?f=%28a%29%5C%20f%5E%7B-1%7D%28-15%29%20%3D%20-6)
![(b)\ f^{-1}(4) + f(9)=0](https://tex.z-dn.net/?f=%28b%29%5C%20f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D0)
Step-by-step explanation:
Given
The attached table
![(a)\ f^{-1}(-15)](https://tex.z-dn.net/?f=%28a%29%5C%20f%5E%7B-1%7D%28-15%29)
This represents an inverse function.
So, we look into x row for its value.
i.e.
![f^{-1}(-15) = -6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28-15%29%20%3D%20-6)
![(b)\ f^{-1}(4) + f(9)](https://tex.z-dn.net/?f=%28b%29%5C%20f%5E%7B-1%7D%284%29%20%2B%20f%289%29)
Just like (a)
---- by looking into the x rows
![f(9) = 11](https://tex.z-dn.net/?f=f%289%29%20%3D%2011)
So:
![f^{-1}(4) + f(9)=-11 + 11](https://tex.z-dn.net/?f=f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D-11%20%2B%2011)
![f^{-1}(4) + f(9)=0](https://tex.z-dn.net/?f=f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D0)
Answer:
50
Step-by-step explanation:
because when we round off it to the nearest ten it is more nearest to the 50 than 60
Answer:
18.4 , 1.84, 3.68, 0.368
Step-by-step explanation:
I I could be completely wrong I've never done this before but I believe the numbers are doubled (multiplied by 2) then divided by 10.
Hope this helps!
