integral from 0 to 1 of (2-3x)^4

\int_{0}^{1} (2 - 3 x)^{4} d x

\frac{11}{5}

Decimal

2.2

Solution steps

\int_{0}^{1} (2 - 3 x)^{4} d x

Apply u-substitution

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

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

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

Take the constant out:

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

= - (- \frac{1}{3} \cdot \int_{- 1}^{2} u^{4} d u)

Apply the Power Rule

= - (- \frac{1}{3} [\frac{u ^{5}}{5}]_{- 1}^{2})

Simplify

= \frac{1}{3} [\frac{u ^{5}}{5}]_{- 1}^{2}

Compute the boundaries:

\frac{33}{5}

= \frac{1}{3} \cdot \frac{33}{5}

Simplify

= \frac{11}{5}
