Question

On what interval(s) is the function `f(x)=5/x+58` increasing?

Answer 1

`f` is not `uarr` in any interval contained in `RR-{0}.`

Explanation:

Recall that, a function (fun.)

`f" is increasing "(uarr), if f'(x) > 0.`

For given fun. `f," we have, "f'(x)=-5/x^2 < 0, AA x in RR-{0}.`

Hence, it is not `uarr` in any interval contained in `RR-{0}.`
