integral from 0 to 3 of (4-x^2)

Solution

\int_{0}^{3} (4 - x^{2}) d x

Solution

3

Solution steps

\int_{0}^{3} 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_{0}^{3} 4 d x - \int_{0}^{3} x^{2} d x

\int_{0}^{3} 4 d x = 12

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

= 12 - 9

Simplify

= 3
