Câu hỏi: Nếu $\int\limits_{0}^{2}{f\left( x \right)\text{d}x}=7;\int\limits_{0}^{5}{f\left( x \right)\text{d}x}=3$ thì $\int\limits_{2}^{5}{f\left( x \right)\text{d}x}$ bằng
A. $4.$
B. $10.$
C. $-4.$
D. $-10.$
A. $4.$
B. $10.$
C. $-4.$
D. $-10.$
$\int\limits_{2}^{5}{f\left( x \right)\text{d}x}=\int\limits_{2}^{0}{f\left( x \right)}dx+\int\limits_{0}^{5}{f\left( x \right)dx}=-7+3=-4$
Đáp án C.
