integral from-4 to 2 of 2x+4

Solution

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

Solution

12

Solution steps

\int_{- 4}^{2} 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_{- 4}^{2} 2 x d x + \int_{- 4}^{2} 4 d x

\int_{- 4}^{2} 2 x d x = - 12

\int_{- 4}^{2} 4 d x = 24

= - 12 + 24

Simplify

= 12
