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

Solution

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

Solution

58

Solution steps

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

\int_{2}^{4} 3 x^{2} d x = 56

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

= 56 + 2

Simplify

= 58
