integral from 1 to 3 of 4-x

Solution

\int_{1}^{3} 4 - x d x

Solution

4

Solution steps

\int_{1}^{3} 4 - x d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{3} 4 d x - \int_{1}^{3} x d x

\int_{1}^{3} 4 d x = 8

\int_{1}^{3} x d x = 4

= 8 - 4

Simplify

= 4
