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

Solution

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

Solution

4

Solution steps

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

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

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

= - (- 3) + 1

Simplify

= 4
