integral from 0 to 3 of 3x-7

Solution

\int_{0}^{3} 3 x - 7 d x

Solution

- \frac{15}{2}

+1

Solution steps

\int_{0}^{3} 3 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_{0}^{3} 3 x d x - \int_{0}^{3} 7 d x

\int_{0}^{3} 3 x d x = \frac{27}{2}

\int_{0}^{3} 7 d x = 21

= \frac{27}{2} - 21

Simplify

\frac{27}{2} - 21 : - \frac{15}{2}

= - \frac{15}{2}
