F^-1 (f^-1 (13))=<br>f^-1 (8)​
skelet666 [1.2K]

According to the table, f(x) = 13 when x = 5. This means

f(5)=13\implies f^{-1}(13) = 5

From the table we also see that f(x)=5 when x=-9, so

f(-9)=5\implies f^{-1}(5)=-9

So we have

f^{-1}\left(f^{-1}(13)\right) = f^{-1}(5)=-9

On the other hand, the table shows f(x)=8 when x=-13, or

f(-13)=8\implies f^{-1}(8)=-13

so the given equation is not true.

Aleksandr [31]

Answer:

10 meters.

Step-by-step explanation:

We know the ball travelled a distance of at least 6 meters as that is how far it was dropped.

It rebounded 2/3 of 6 meters, which is 4 meters.

6 meters add 4 meters is 10 meters.
