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

Solution

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

Solution

16

Solution steps

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

\int_{- 1}^{3} 3 x d x = 12

\int_{- 1}^{3} 1 d x = 4

= 12 + 4

Simplify

= 16
