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

Solution

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

Solution

\frac{45}{2}

+1

Decimal Notation

22.5

Solution steps

\int_{- 1}^{4} x + 3 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} x d x + \int_{- 1}^{4} 3 d x

\int_{- 1}^{4} x d x = \frac{15}{2}

\int_{- 1}^{4} 3 d x = 15

= \frac{15}{2} + 15

Simplify

\frac{15}{2} + 15 : \frac{45}{2}

= \frac{45}{2}
