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

Solution

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

Solution

6

Solution steps

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

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

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

= 3 + 3

Simplify

= 6
