If

f\left( x \right) = {2^{2x - 1}}

and

\phi \left( x \right) - {2^x} + 2x\log 2.

If

f'\left( x \right) > \phi '\left( x \right),

then

View answer and explanation

Correct option: C

x > 0

Option C (

x > 0

) is correct because solving the inequality

f'(x) > \phi'(x)

leads to the condition

x > 0

.
