Question

On which of the following intervals is the function f given by strictly decreasing?

(A) (B)

(C) (D) None of these

Open in App

Solution

We have,

In interval

Thus, function f is strictly increasing in interval (0, 1).

In interval

Thus, function f is strictly increasing in interval.

∴ f is strictly increasing in interval.

Hence, function f is strictly decreasing in none of the intervals.

The correct answer is D.
