integral from 1 to 3 of (3x^2+4)

Solution

\int_{1}^{3} (3 x^{2} + 4) d x

Solution

34

Solution steps

\int_{1}^{3} 3 x^{2} + 4 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}^{3} 3 x^{2} d x + \int_{1}^{3} 4 d x

\int_{1}^{3} 3 x^{2} d x = 26

\int_{1}^{3} 4 d x = 8

= 26 + 8

Simplify

= 34
