integral from 1 to 4 of-2x+8

Solution

\int_{1}^{4} - 2 x + 8 d x

Solution

9

Solution steps

\int_{1}^{4} - 2 x + 8 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} 8 d x

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

\int_{1}^{4} 8 d x = 24

= - 15 + 24

Simplify

= 9
