integral from-1 to 2 of (4-x^2)

Solution

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

Solution

9

Solution steps

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

\int_{- 1}^{2} 4 d x = 12

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

= 12 - 3

Simplify

= 9
