integral from 1 to 3 of 3x+2

Solution

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

Solution

16

Solution steps

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

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

\int_{1}^{3} 2 d x = 4

= 12 + 4

Simplify

= 16
