integral from-1 to 5 of 2x+8

Solution

\int_{- 1}^{5} 2 x + 8 d x

Solution

72

Solution steps

\int_{- 1}^{5} 2 x + 8 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}^{5} 2 x d x + \int_{- 1}^{5} 8 d x

\int_{- 1}^{5} 2 x d x = 24

\int_{- 1}^{5} 8 d x = 48

= 24 + 48

Simplify

= 72
