f\left( {2x + 3} \right) = \sin x + {2^x},

then

f\left( {4m - 2n + 3} \right)

is equal to

View answer and explanation

Correct option: D

\sin \left( {2m - n} \right) + {2^{2m - n}}

Option D (

\sin \left( {2m - n} \right) + {2^{2m - n}}

) is correct because it is obtained by substituting x = 2m - n into the given function.
