integral from-2 to 1 of (2x+2)

Solution

\int_{- 2}^{1} (2 x + 2) d x

Solution

3

Solution steps

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

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

\int_{- 2}^{1} 2 d x = 6

= - 3 + 6

Simplify

= 3
