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

Solution

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

Solution

16

Solution steps

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

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

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

= 4 + 12

Simplify

= 16
