For function f(x) = [x] − 5 the value of f(8.6) is 3.
The correct answer is option (A)
What is greatest integer function?
"This function rounds up the number to the most neighboring integer less than or equal to the provided number."
For given question,
We have been given a greatest integer function.
f(x) = [x] − 5
We need to find the value of f(8.6)
We know that the greatest integer function rounds up the number to the most neighboring integer less than or equal to the provided number.
For x = 8.6,
[8.6] = 8
So, the value of given function would be,
⇒ f(8.6) = [8.6] − 5
⇒ f(8.6) = 8 - 5
⇒ f(8.6) = 3
Therefore, for function f(x) = [x] − 5 the value of f(8.6) is 3.
