Cho \[\int {f\left( x \right)dx = } F\left( x \right),{\rm{ }}\int {g\left( x \right)dx = G\left( x \right)} \]. Khi đó, \[I = \int {\left[ {2g\left( x \right) - f\left( x \right)} \right]dx} \] bằng

Đáp án đúng là: C

Ta có: \[I = \int {\left[ {2g\left( x \right) - f\left( x \right)} \right]dx} \]

\[I = \int {2g\left( x \right)dx} - \int {f\left( x \right)dx} \]

\[I = 2\int {g\left( x \right)dx} - \int {f\left( x \right)dx} \]

\[I = 2G\left( x \right) - F\left( x \right)\]
