integral from-1 to 5 of (1+3x)

Solution

\int_{- 1}^{5} (1 + 3 x) d x

Solution

42

Solution steps

\int_{- 1}^{5} 1 + 3 x 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} 1 d x + \int_{- 1}^{5} 3 x d x

\int_{- 1}^{5} 1 d x = 6

\int_{- 1}^{5} 3 x d x = 36

= 6 + 36

Simplify

= 42
