integral from-1 to 2 of (2x+3)

Solution

\int_{- 1}^{2} (2 x + 3) d x

Solution

12

Solution steps

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

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

\int_{- 1}^{2} 3 d x = 9

= 3 + 9

Simplify

= 12
