integral from-1 to 1 of 2x+1

Solution

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

Solution

2

Solution steps

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

\int_{- 1}^{1} 2 x d x = 0

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

= 0 + 2

Simplify

= 2
