If f(x) = [xl-5, what is f(8.6)?
Fynjy0 [20]

Answer:

  3 or 4, depending on the intended meaning of [x]

Step-by-step explanation:

Perhaps you mean ...

  \displaystyle f(x)= \lfloor x\rfloor -5\\\\f(8.6)=\lfloor 8.6\rfloor-5=8-5=3

__

On the other hand, perhaps you mean ...

  \displaystyle f(x)=\lceil x\rceil -5\\\\f(8.6)=\lceil 8.6\rceil-5=9-5=4
