Question

In the procedure for finding intervals, which conclusion is correct when \[f'(x)<0\]?

विकल्प

• \[f\] is constant.

• \[f\] is strictly increasing.

• \[f\] is increasing.

• \[f\] is decreasing.

Answer 1

A negative derivative indicates that the output decreases as the input increases. Therefore \[f\] is decreasing on that interval.
