integral from 1 to 4 of 2x+1

Solution

\int_{1}^{4} 2 x + 1 d x

Solution

18

Solution steps

\int_{1}^{4} 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_{1}^{4} 2 x d x + \int_{1}^{4} 1 d x

\int_{1}^{4} 2 x d x = 15

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

= 15 + 3

Simplify

= 18
