Câu hỏi: Biết \(\mathop {\lim }\limits_{x \to {x_0}} f\left( x \right) =  - 2\) và \(\mathop {\lim }\limits_{x \to {x_0}} g\left( x \right) = 7\). Khi đó \(I = \mathop {\lim }\limits_{x \to {x_0}} \left[ {f\left( x \right) - 3g\left( x \right)} \right]\).

A \(I = 23\)                              

B \(I = 19\)                                

C \(I =  - 19\)                             

D \(I =  - 23\)
