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

Solution

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

Solution

14

Solution steps

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

\int_{1}^{3} 2 x d x = 8

\int_{1}^{3} 3 d x = 6

= 8 + 6

Simplify

= 14
