integral from-1 to 4 of (3x-2)

Solution

\int_{- 1}^{4} (3 x - 2) d x

Solution

\frac{25}{2}

+1

Solution steps

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

\int_{- 1}^{4} 3 x d x = \frac{45}{2}

\int_{- 1}^{4} 2 d x = 10

= \frac{45}{2} - 10

Simplify

\frac{45}{2} - 10 : \frac{25}{2}

= \frac{25}{2}
