integral from 1 to 4 of 2x-4

Solution

\int_{1}^{4} 2 x - 4 d x

Solution

3

Solution steps

\int_{1}^{4} 2 x - 4 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}^{4} 2 x d x - \int_{1}^{4} 4 d x

\int_{1}^{4} 2 x d x = 15

\int_{1}^{4} 4 d x = 12

= 15 - 12

Simplify

= 3
