Cho biết \(\int\limits_1^3 {f\left( x \right){\rm{d}}x} = - \,2,\,\,\int\limits_1^4 {f\left( x \right){\rm{d}}x} = 3\) và \(\int\limits_1^4 {g\left( x \right){\rm{d}}x} = 7.\) Khẳng định nào sau đây là sai ?
A.\(\int\limits_1^4 {\left[ {f\left( x \right) + g\left( x \right)} \right]{\rm{d}}x} = 10.\)
B.\(\int\limits_3^4 {f\left( x \right){\rm{d}}x} = 1.\)
C.\(\int\limits_3^4 {f\left( x \right){\rm{d}}x} = \,5.\)
D.\(\int\limits_1^4 {\left[ {4f\left( x \right) - 2g\left( x \right)} \right]{\rm{d}}x} = - \,2.\)
A.\(\int\limits_1^4 {\left[ {f\left( x \right) + g\left( x \right)} \right]{\rm{d}}x} = 10.\)
B.\(\int\limits_3^4 {f\left( x \right){\rm{d}}x} = 1.\)
C.\(\int\limits_3^4 {f\left( x \right){\rm{d}}x} = \,5.\)
D.\(\int\limits_1^4 {\left[ {4f\left( x \right) - 2g\left( x \right)} \right]{\rm{d}}x} = - \,2.\)
