integral from-2 to 1 of 2x+4

Solution

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

Solution

9

Solution steps

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

\int_{- 2}^{1} 2 x d x = - 3

\int_{- 2}^{1} 4 d x = 12

= - 3 + 12

Simplify

= 9
