integral from 0.75 to 1 of 2x

\int_{0.75}^{1} 2 x d x

0.4375

Solution steps

\int_{0.75}^{1} 2 x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{0.75}^{1} x d x

Apply the Power Rule

= 2 [\frac{x ^{2}}{2}]_{0.75}^{1}

Simplify

= 2 [0.5 x^{2}]_{0.75}^{1}

Compute the boundaries:

0.21875

= 2 \cdot 0.21875

Simplify

= 0.4375
