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

Solution

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

Solution

- 9

Solution steps

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

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

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

= 3 - 12

Simplify

= - 9
