Câu hỏi: Cho \(\int\limits_{ - 1}^2 {f\left( x \right)dx = 2,\int\limits_{ - 1}^2 {g\left( x \right)dx =  - 1} } \). Tính \(I = \int\limits_{ - 1}^2 {\left[ {x + 2f\left( x \right) - 3g\left( x \right)} \right]dx} \)

A. \(I = \frac{{17}}{2}\)

B. \(I = \frac{{7}}{2}\)

C. \(I = \frac{{5}}{2}\)

D. \(I = \frac{{11}}{2}\)
