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

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

12

Solution steps

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

\int_{- 1}^{3} x^{3} d x = 20

\int_{- 1}^{3} 3 x^{2} d x = 28

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

= - 20 + 28 + 4

Simplify

= 12
