Problem Identify the correct property of indefinite integrals for the sum of two functions f ( x ) f(x) f ( x ) and g ( x ) g(x) g ( x ) .
(a) ∫ [ f ( x ) + g ( x ) ] d x = ∫ f ( x ) d x ⋅ ∫ g ( x ) d x \displaystyle \int [f(x)+g(x)]\,dx = \int f(x)\,dx \cdot \int g(x)\,dx ∫ [ f ( x ) + g ( x )] d x = ∫ f ( x ) d x ⋅ ∫ g ( x ) d x
(b) ∫ [ f ( x ) + g ( x ) ] d x = ∫ f ( x ) d x + ∫ g ( x ) d x \displaystyle \int [f(x)+g(x)]\,dx = \int f(x)\,dx + \int g(x)\,dx ∫ [ f ( x ) + g ( x )] d x = ∫ f ( x ) d x + ∫ g ( x ) d x
(c) ∫ [ f ( x ) + g ( x ) ] d x = ∫ f ( x ) d x − ∫ g ( x ) d x \displaystyle \int [f(x)+g(x)]\,dx = \int f(x)\,dx - \int g(x)\,dx ∫ [ f ( x ) + g ( x )] d x = ∫ f ( x ) d x − ∫ g ( x ) d x
(d) ∫ [ f ( x ) + g ( x ) ] d x = ∫ [ f ( x ) g ( x ) ] d x \displaystyle \int [f(x)+g(x)]\,dx = \int [f(x)g(x)]\,dx ∫ [ f ( x ) + g ( x )] d x = ∫ [ f ( x ) g ( x )] d x
