integral from 3 to 4 of (2x+9)

Solution

\int_{3}^{4} (2 x + 9) d x

Solution

16

Solution steps

\int_{3}^{4} 2 x + 9 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_{3}^{4} 2 x d x + \int_{3}^{4} 9 d x

\int_{3}^{4} 2 x d x = 7

\int_{3}^{4} 9 d x = 9

= 7 + 9

Simplify

= 16
