integral from 2 to 7 of 2x+1

Solution

\int_{2}^{7} 2 x + 1 d x

Solution

50

Solution steps

\int_{2}^{7} 2 x + 1 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_{2}^{7} 2 x d x + \int_{2}^{7} 1 d x

\int_{2}^{7} 2 x d x = 45

\int_{2}^{7} 1 d x = 5

= 45 + 5

Simplify

= 50
