integral from-1 to 1 of 3x^2-4x+7

Solution

\int_{- 1}^{1} 3 x^{2} - 4 x + 7 d x

Solution

16

Solution steps

\int_{- 1}^{1} 3 x^{2} - 4 x + 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}^{1} 3 x^{2} d x - \int_{- 1}^{1} 4 x d x + \int_{- 1}^{1} 7 d x

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

\int_{- 1}^{1} 4 x d x = 0

\int_{- 1}^{1} 7 d x = 14

= 2 - 0 + 14

Simplify

= 16
