integral from-2 to 4 of 3x-9

Solution

\int_{- 2}^{4} 3 x - 9 d x

Solution

- 36

Solution steps

\int_{- 2}^{4} 3 x - 9 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_{- 2}^{4} 3 x d x - \int_{- 2}^{4} 9 d x

\int_{- 2}^{4} 3 x d x = 18

\int_{- 2}^{4} 9 d x = 54

= 18 - 54

Simplify

= - 36
