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

Solution

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

Solution

10

Solution steps

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

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

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

= 2 + 8

Simplify

= 10
