integral from 4 to 6 of 3x-9

Solution

\int_{4}^{6} 3 x - 9 d x

Solution

12

Solution steps

\int_{4}^{6} 3 x - 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_{4}^{6} 3 x d x - \int_{4}^{6} 9 d x

\int_{4}^{6} 3 x d x = 30

\int_{4}^{6} 9 d x = 18

= 30 - 18

Simplify

= 12
