If

f\left( x \right) = {\log _e}\left\{ {\frac{{u\left( x \right)}}{{\upsilon \left( x \right)}}} \right\},u\left( 1 \right) = \upsilon \left( 1 \right)

and

u'\left( 1 \right) = \upsilon '\left( 1 \right) = 2

, then

f'\left( 1 \right)

is equal to

View answer and explanation

Correct option: A

0

Option A (0) is correct because when

u(1) = v(1)

and

u'(1) = v'(1) = 2

, the derivative

f'(1)

becomes zero.
