Which expression represents the derivative of f(x)=e2xcos(3x)f(x) = e^{2x} \cos(3x)f(x)=e2xcos(3x)?
e2x(2cos(3x)−3sin(3x))e^{2x}(2\cos(3x) - 3\sin(3x))e2x(2cos(3x)−3sin(3x))
e2x(2cos(3x)+3sin(3x))e^{2x}(2\cos(3x) + 3\sin(3x))e2x(2cos(3x)+3sin(3x))
2e2xcos(3x)−3sin(3x)2e^{2x} \cos(3x) - 3\sin(3x)2e2xcos(3x)−3sin(3x)
e2xcos(3x)−e2xsin(3x)e^{2x} \cos(3x) - e^{2x} \sin(3x)e2xcos(3x)−e2xsin(3x)
