integral from 0 to 3 of (-x^2+9)

Solution

\int_{0}^{3} (- x^{2} + 9) d x

Solution

18

Solution steps

\int_{0}^{3} - x^{2} + 9 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_{0}^{3} x^{2} d x + \int_{0}^{3} 9 d x

\int_{0}^{3} x^{2} d x = 9

\int_{0}^{3} 9 d x = 27

= - 9 + 27

Simplify

= 18
