integral from-1 to 2 of-x^2+7

Solution

\int_{- 1}^{2} - x^{2} + 7 d x

Solution

18

Solution steps

\int_{- 1}^{2} - x^{2} + 7 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}^{2} x^{2} d x + \int_{- 1}^{2} 7 d x

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

\int_{- 1}^{2} 7 d x = 21

= - 3 + 21

Simplify

= 18
