The value of f(8.6) is -5.
Given that
If f(x) = − 5,
We have to determine
What is f(8.6)?
According to the question
This function is independent of x.
There is no term associated with x on the function.
f(x) = − 5,
The given is not dependent on the variable it is an independent function.
Then,

Hence, the value of f(8.6) is -5.
