Cho \(\int {f\left( x \right)dx = F\left( x \right...

Câu hỏi: Cho \(\int {f\left( x \right)dx = F\left( x \right) + C} \). Khi đó \(a \ne 0\), ta có \(\int {f\left( {ax + b} \right)dx} \) bằng: 

A. \(\frac{1}{{2a}}F\left( {ax + b} \right) + C\)

B. \(aF\left( {ax + b} \right) + C\)

C. \(\frac{1}{{a}}F\left( {ax + b} \right) + C\)

D. \(F\left( {ax + b} \right) + C\)
