integral from-1 to 4 of (2x+1)

Solution

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

Solution

20

Solution steps

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

\int_{- 1}^{4} 2 x d x = 15

\int_{- 1}^{4} 1 d x = 5

= 15 + 5

Simplify

= 20
