integral from 0 to 3 of (2x+1)

Solution

\int_{0}^{3} (2 x + 1) d x

Solution

12

Solution steps

\int_{0}^{3} 2 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_{0}^{3} 2 x d x + \int_{0}^{3} 1 d x

\int_{0}^{3} 2 x d x = 9

\int_{0}^{3} 1 d x = 3

= 9 + 3

Simplify

= 12
