integral from 3 to 7 of e^x-3x

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

e^{7} - e^{3} - 60

Decimal

1016.54762 \dots

Solution steps

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

\int_{3}^{7} e^{x} d x = e^{7} - e^{3}

\int_{3}^{7} 3 x d x = 60

= e^{7} - e^{3} - 60
