integral from 0 to 2 of 9x^2

\int_{0}^{2} 9 x^{2} d x

24

Solution steps

\int_{0}^{2} 9 x^{2} d x

Take the constant out:

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

= 9 \cdot \int_{0}^{2} x^{2} d x

Apply the Power Rule

= 9 [\frac{x ^{3}}{3}]_{0}^{2}

Compute the boundaries:

\frac{8}{3}

= 9 \cdot \frac{8}{3}

Simplify

= 24
